These super easy, healthy tacos are completely delicious. (This is an adaptation of a recipe by Layla for Gimme Delicious.) The calorie count in this recipe is based on a regular flour tortilla, but if you want to cut out 100 calories per taco, try using low-carb, high fiber, low calorie tortillas. I love the "Ole Mexican Xtreme Wellness" tortillas that you can find at Walmart. They taste great. You can also substitute plain yogurt for the sour cream to reduce the fat. Enjoy!
