Preheat oven to 400 degrees F. Cut bread into ~ 1-inch cubes. Place on baking sheet, and drizzle 1 tablespoon of olive oil over bread cubes. Use clean hands to spread oil over bread, and coat well. Bake in oven for ~ 5 minutes, or until light golden brown. Remove from oven and baking sheet, and place in large salad bowl.

Add chopped salad greens, sliced tomatoes, chopped cucumber and bell peppers to bowl with bread cubes. Add chopped olives, crumbled feta, and chopped fresh herbs. Drizzle remaining  olive oil over ingredients, along with lemon juice, and toss well. Top with freshly ground black pepper & salt if desired {I didn't use any salt because the feta cheese and kalamata olives provide enough flavor}.
