Preheat the oven to 400° F and spray a 12-cup muffin tin with cooking spray.

In a large skillet, heat some olive oil over medium heat. Add the diced onions and sauté until they are tender.

Add the ground beef and season with the chili powder, cumin, paprika, garlic powder, onion powder, salt, and black pepper. Cook until the beef is browned, about 3-4 minutes.

Stir in the canned tomatoes and continue cooking until most of the liquid is absorbed, about another 5-7 minutes.

Place one wonton wrapper in the center of each muffin cup, pressing down gently.

Add a small layer of cheese on top, followed by another wonton wrapper. Press down again.

Spoon roughly one tablespoon of the ground beef mixture into each cup and sprinkle with the remaining cheese.

Bake in the preheated oven for 13-17 minutes or until the wontons are golden and crispy. Check around the 10-minute mark.

Run a knife around the edge of each cup to pop them out and add your favorite toppings before serving.
