Prep the Base: Preheat your oven to 350°F. Arrange the wonton wrappers in a 12-cup muffin pan and lightly spray them with cooking spray.
Bake for Crispiness: Place the pan in the oven and bake for 5 minutes until the wrappers begin to crisp. Remove from the oven and set aside.
Cook the Filling: In a medium pan, heat the vegetable oil over medium-low heat. Add the ground meat and cook until fully browned, breaking it apart as it cooks. Stir in the taco seasoning and mix well before removing from heat.
Assemble the Cups: Evenly distribute the cooked meat among the crispy wonton cups. Top each with shredded cheese, lettuce, a dollop of guacamole, salsa, and sour cream.
Serve: Enjoy immediately for the best crunch and flavor!
