Preheat your oven to 375°F (190°C) and line a baking sheet with baking paper.
Mix the cheddar, mozzarella, and Parmesan together.
Place 2-tablespoon portions of the cheese mixture onto the lined baking sheet, forming small circles (about 4 inches wide).
Bake for 5-7 minutes until the edges are bubbly and golden.
Let cool for 1 minute until they are flexible but not too firm.
While the cheese shells bake, heat a pan over medium heat.
Add ground beef, garlic, and minced onion, cooking until the beef is browned and the onions are soft.
Stir in chili flakes, paprika, cumin, garlic powder, and salt.
Cook for another 2-3 minutes, then remove from heat.
Spoon about 1 tablespoon of the beef mixture onto each melted cheese round.
Carefully roll each one into a taquito shape, seam side down.
Let them set for a few minutes to hold their shape.
Serve warm with sour cream, guacamole, or a low-carb salsa for dipping. I served mine with a couple of chopped cherry tomatoes, green onions, and fresh cilantro which is my favorite!
