Pre-heat oven to 400 degrees. Place cranberries and orange juice in a medium sauce pan, and heat until boiling. Reduce heat and simmer for approximately 5 minutes, or until cranberries have "popped" and are cooked through.
Add quinoa, milk, maple syrup, vanilla, and orange zest to orange juice and cranberry mixture, and heat until boiling. Turn heat down to medium low and cover ~2/3 of the pan. Cook mixture for ~ 30 minutes, or until pudding consistency is achieved. Stir every 3-5 minutes to prevent sticking. While quinoa is cooking, place sliced almonds on a baking sheet, and bake in oven for 4-5 minutes, or until lightly brown and toasted.
Divide quinoa pudding equally in to 7 serving dishes, and top with toasted almonds. Serve warm, or you may chill pudding in fridge, and serve cold.
