Making Mini Loaded Taco Cups is a straightforward process. Follow these steps to create a delicious appetizer:

1. Preheat the Oven:
   • Preheat your oven to 375°F (190°C).
2. Prepare the Taco Shells:
   • If using mini taco shells, place them on a baking tray. For wonton wrappers, press each wrapper into the wells of a muffin tin to create a cup shape.
3. Cook the Ground Beef:
   • In a large skillet, heat olive oil over medium heat. Add chopped onions and minced garlic, sauté until onions are translucent.
   • Add ground beef to the skillet. Cook until browned, breaking it apart with a spatula.
   • Drain excess fat and return the skillet to the heat.
4. Season the Beef:
   • Stir in taco seasoning and tomato sauce. Mix well to combine.
   • Simmer for a few minutes until the sauce thickens. Season with salt and pepper to taste.
5. Assemble the Taco Cups:
   • Spoon the seasoned beef mixture into each taco shell or wonton cup, filling them about three-quarters full.
6. Add Cheese:
   • Sprinkle shredded cheddar cheese on top of the beef mixture in each cup.
7. Bake:
   • Place the tray or muffin tin in the preheated oven. Bake for 10-12 minutes or until the cheese is melted and the shells are crispy.
8. Garnish and Serve:
   • Remove from the oven and let cool slightly. Top with shredded lettuce, diced tomatoes, a dollop of sour cream, and garnish with cilantro and jalapeños if desired.
