Preheat oven to 375°F (190°C)
If using tortillas, cut into smaller rounds (about 3–4 inches) using a cookie cutter or glass.Press each round or wonton wrapper into a greased muffin tin to form a cup shape.Lightly brush with olive oil. Bake for 8–10 minutes until golden and crisp. Let cool.
Cook ground beef or turkey in a skillet on medium-high heat until the internal temperature reaches 165 degrees Fahrenheit. Drain.Place the cooked protein back in the skillet with taco seasoning and a splash of water. Simmer for 2–3 minutes. Spoon seasoned filling into each taco cup and top with shredded cheese.
Place toppings separately in small containers, bowls, or on a serving tray so kids can build their taco cups at the table.
