Preheat your oven to 425°F (220°C). Spread frozen tater tots on a baking sheet and bake for 20-25 minutes, flipping halfway through.

While tater tots are baking, heat a skillet over medium-high heat. Add ground beef and cook until browned (6-8 minutes). Drain excess grease, then sprinkle taco seasoning over the beef, adding a splash of water.

Warm the flour tortillas in a dry skillet over medium heat for 30 seconds on each side, or wrap in damp paper towels and microwave for 20 seconds.

Fill each tortilla with nacho cheese sauce, seasoned beef, crispy tater tots, cheddar cheese, and sour cream.

Fold the sides of the tortilla inward and roll tightly, tucking in the filling. Cut diagonally in half for serving.
