Inspiration for Smoked Salmon Sandwiches

I’ve been taking my dad to Costco lately. He loves going, but my mom, not so much. He has dementia and forgets all the food they have on hand. And my mom ends up being the “bad guy,” telling him what he can’t buy.ย 

Fortunately, I don’t mind being the bad guy, and we always have fun together. He’s happy shopping with me, my mom’s happy she gets time alone at home, and I get to do my grocery shopping. It’s a win, win, win!

Long story short, I picked up some Costco Smoked Salmon on our latest shopping trip and was inspired to make this yummy smoked salmon sandwich.

Not only is salmon a delicious source of protein, but it’s also a fantastic source of omega-3s, an essential component of theย MIND dietย forย Alzheimer’s prevention.ย 

Why This Is Such a Good Sandwich


  • SATISFYING– The protein and fiber in this delicious sandwich helps keep you full and satisfied.
  • NUTRIENT DENSE – This sandwich is packed with omega-3 fats and antioxidants, yet only has 500 calories.
  • SO EASY TO MAKE – Got 10 minutes? Yes, you do! Make this smoked salmon sandwich!!!

Ingredients & Substitutions

Ingredients on a sheet pan for making a smoked salmon sandwich. These include gluten free bread, leafy greens, smoked salmon, red onion, avocado, hemp seeds, and lemon.

You can adapt this smoked salmon sandwich to your tastes with whatever fresh vegetables or simple ingredients you have on hand. Here are some ideas:

  • Bread.ย I love dense bread for this smoked salmon sandwich, like Happy Campers Gluten-Free Buckwheat Molasses Bread. If you aren’t following a gluten-free diet, try whole wheat bread, like Dave’s Killer Bread. Rye bread or pumpernickel bread pairs well with salmon.
  • Avocado.ย You can swap the avocado for another source of fat, like goat cheese, sour cream, or cream cheese. Feta cheese is a natural go-to with smoked salmon. Or, for aย low FODMAPย version, drizzle a little extra virgin olive oil or avocado oil on your toast.ย 
  • Leafy greens.ย Greens add nutrients and lots of fresh flavor. I use baby spinach and arugula, but this smoked salmon sandwich would also be tasty with baby kale, microgreens, Swiss chard, Spring lettuce mix, beet greens, watercress, or Romaine lettuce. Fresh herbs like basil, cilantro, or parsley can also be used in place of the leafy greens.
  • Red Onion.ย Chopped red onion or red onion slices add another layer of flavor and nutrition to this sandwich. Swap them with sliced green onion tops or chives for a low FODMAP option.ย 
  • Seasonings.ย Freshly Ground Black Pepper and lemon zest or juice. I don’t add salt since smoked salmon is high in sodium; however, add a little salt if you like.
  • Hemp Seeds. For more healthy fats and fiber, pumpkin, sesame, sunflower, chia, basil, or poppy seeds would be equally nutritious and delicious!
  • Optional Toppings.ย Chopped fresh dill, microgreens, cucumber slices, capers, or chopped chives.ย 

How to Make Your Sandwich in 3 Easy Steps

Happy Campers gluten free buckwheat molasses bread.
  1. Toast two slices of bread.ย 
  2. Slice the avocado and layer it on each slice of bread. Top with cold-smoked salmon.
  3. Add your leafy greens, chopped onion, seasonings, hemp seeds, and any optional toppings.

โ€‹Entertaining Tip! Make salmon tea sandwiches for a party. Slice each piece of bread into 4 triangles and add toppings.

Is smoked salmon healthy?

Smoked salmon is rich inย anti-inflammatory omega-3ย fatty acids, which makes it a healthy choice. One caveat, however.

Smoked salmon contains quite a bit more sodium than plain salmon, so I recommend eating it in moderation-perhaps once 1 week, especially if you’re following a DASH diet, have high blood pressure, or are salt sensitive.ย 

The rest of the time, choose unsmoked salmon to get your omega-3s. Canned salmon is also a healthy pantry staple and would be equally delicious on this salmon sandwich!

Nutrition

Two open-faced sandwiches have approximately 500 calories, 30 grams of protein, 10 grams of fiber, and 23 grams of fat (only 3 grams of saturated fat).

Prep Time: 10 minutes
Total Time: 10 minutes
Servings: 1 serving

Ingredients

  • 2 slices gluten free bread, i.e. Happy Campers Buckwheat Molasses
  • 1/4 large avocado, peeled, pitted, and sliced
  • 1 cup leafy greens, i.e. arugula, baby spinach, kale, etc.
  • 4 ounces smoked salmon
  • 2 tablespoons red onion, chopped
  • 2 teaspoons hemp seeds
  • 1 squeeze fresh lemon juice

Instructions

  • Toast the bread.
  • Slice the avocado and layer on top of toasted bread slices, then top with smoked salmon.
  • Top avocado toast with leafy greens, chopped onion, and hemp seeds. Add a squeeze of fresh lemon juice before serving.

Notes

Low FODMAP Substitutions:

  • Omit chopped red onion. For additional flavor, top with chopped green onion tops.
  • Limit avocado to 1/8 instead of 1/4. Feel free to add a drizzle extra virgin olive oil or avocado oil on your toast.

Other additions & substitutions:

  • Add any favorite leafy greens. I used a combo of baby spinach and arugula, but this smoked salmon sandwich would also be tasty with baby kale, microgreens, Swiss chard, Spring lettuce mix, beet greens, watercress, or Romaine lettuce. Fresh herbs like basil, cilantro, or parsley can also be used in place of leafy greens.
  • Swap out/add more toppings!!! Capers are a popular pairing with smoked salmon. Try different seeds in place of the hemp seeds. Pumpkin, sesame, sunflower, chia, or poppy seeds would all be just as nutritious and equally delicious.
