Preheat your oven to 375°F (190°C). Lightly spray a 12-cup muffin tin with cooking spray.

In a large skillet over medium-high heat, brown the ground beef. Drain off any excess grease.

Add the taco seasoning and water to the skillet with the browned beef. Stir well to combine. Bring the mixture to a simmer and cook for about 5 minutes, or until the sauce has thickened slightly.

Place one wonton wrapper in each muffin cup, pressing it gently into the bottom and up the sides to form a cup shape.

Spoon a generous amount of the seasoned beef mixture into each wonton cup. Then, sprinkle each cup with a layer of shredded cheese.

Bake for 10-12 minutes, or until the wonton wrappers are golden brown and crispy, and the cheese is melted and bubbly.

Remove the taco cups from the oven and let them cool for a few minutes before adding your favorite toppings.

Serve and enjoy warm.
