Want to add omega-3 to your diet but don't like fish? Try crab instead. Crab meat also has omega-3 fatty acids. Combine canned crab with citrus vinaigrette and serve over salad. Keep salt and calories low by making your own dressing. It's as easy as whisking together 1/4 cup lime or lemon juice, 1/4 cup rice wine vinegar, 1 teaspoon sugar and your favorite herbs.
