Prepare the Filling: Cook your protein (ground beef, chicken, or pork) in a skillet, adding taco seasoning and water until fully cooked. If using beans or veggies, sauté them with taco seasoning.
Prepare the Tortillas: Warm the mini tortillas in a skillet or microwave until pliable. This will help prevent cracking while folding.
Shape the Tacos: Fold each tortilla into a U-shape and secure them lightly. You can use a muffin tin to hold the shape if needed.
Fill the Tacos: Spoon your protein or vegetable filling into each taco shell and top with shredded cheese.
Air Fry: Preheat the air fryer to 375°F (190°C). Lightly spray the tacos with olive oil or cooking spray. Place them in the air fryer basket in a single layer. Cook for 5-7 minutes, flipping halfway through, until they are golden and crispy.
Serve: Once cooked, remove the tacos from the air fryer, add your favorite toppings, and serve immediately.
