Remember to brush your teeth after this one. Over a bed of mixed greens or spinach, add 1/2-1 sliced avocado, 1/2-1 can sardines (with oil), 1/2-1 sliced tomatoes or handful cherry tomatoes, a squeeze of lemon juice, and any other chopped vegetables of choice (for added crunch, use celery or carrots). Top with a handful of pumpkin seeds, and sea salt and black pepper to taste.
