If you are looking for a lighter Cinco de Mayo meal, try this vegetarian taco salad. Instead of ground beef or grilled chicken, this recipe calls for soyrizo. You should be able to find it in your local grocery store or health foods store. The salad is mixed with chunks of creamy avocado, tortilla chips, and salty olives. Instead of dressing, top your vegetarian taco salad with low-fat sour cream and fresh tomato salsa.
