01 - Preheat your oven to 375°F (190°C).
02 - Using a 2.5-inch round cutter, carefully cut two mini circles from each tortilla. Lightly coat both sides of the tortilla rounds with olive oil spray, then gently press them into a mini muffin tin to shape into small taco shells.
03 - Bake the prepared tortilla shells for 8 to 10 minutes, or until they achieve a golden, crisp texture. Remove from oven and allow to cool completely.
04 - While the shells are baking, heat a skillet over medium heat. Add the ground beef and cook for 3 to 4 minutes, actively breaking it apart with a spoon. Introduce the finely chopped onion and minced garlic, continuing to sauté for an additional 2 to 3 minutes until softened.
05 - Incorporate the taco seasoning, smoked paprika, ground cumin, salt, and black pepper into the beef mixture. Stir in the tomato paste and water. Continue to cook, stirring frequently, for approximately 5 minutes, until the mixture visibly thickens. Remove the skillet from heat.
06 - Fill each cooled taco shell with a spoonful of the prepared beef mixture. Garnish generously with shredded cheese, shredded lettuce, diced tomatoes, a small dollop of sour cream, guacamole, and fresh cilantro leaves.
07 - Serve the mini tacos immediately, accompanied by fresh lime wedges.
