Brown one package turkey breast (the breast part is essential) in a non-stick pan. I use a tiny bit of EVOO, but you can use cooking spray too.
Once turkey is nearly browned, add 1 Tbsp of chili powder and 1 tsp. cumin. Mix well.
Then add 1 jar prepared salsa. I use mild for my kids.
You can also add some chopped mushrooms, red peppers, corn, etc. while the meat simmers.
Let it simmer for 10 minutes or more. Mix every 10 minutes if you simmer for longer.
Fill shells, top with chopped lettuce, grated cheese, sliced black olives and avocado chunks.
YUM!
