Preheat the oven to 180°C (350°F).

Lightly grease a muffin tray and press small tortillas into each muffin cup to create taco bowls. Bake for 10-12 minutes until crispy and golden. Remove and set aside.

In a large pan, heat a tablespoon of oil over medium heat. Add the ground beef and cook until browned, about 6-8 minutes.

Stir in taco seasoning and a splash of water. Simmer for 3-4 minutes until the beef is well coated and the sauce thickens.

While the beef is cooking, prepare the homemade salsa by combining chopped tomatoes, onions, lime juice, and cilantro in a bowl. Season with salt and pepper to taste.

Spoon the seasoned beef mixture into the baked tortilla cups.

Top each taco cup with grated cheese and a spoonful of the homemade salsa.

Serve immediately with extra salsa on the side.
