Preheat the oven to 400 degrees. Heat a large pan over medium high heat. Add the beef and zucchini to the pan. Use a spatula to break up the meat, stirring constantly. Add the taco seasoning and salt/pepper to taste. Cook the meat for about 5-6 minutes or until cooked through. Remove from heat.

Coat a 12-cup muffin tin with cooking spray. Place one wonton wrapper into the bottom of each muffin cup. Spoon approximately 1 tablespoon of the meat mixture into each cup and top with about 2 teaspoons of cheese.

Place a second wonton layer on top of the cheese, then add the remaining meat and cheese across all the muffin cups. Bake for 10-12 minutes or until edges are browned and cheese is melted.

Top each taco cup with a small dollop of sour cream, if desired, and Enjoy!
