Spread half the tater tots all over a baking sheet and half over another.
Bake both pans for 30 minutes.
Sprinkle half of the taco meat over the cooked tater tots, then half of the cheese.
Remove the second pan of tater tots and pour over the top of the others.
Sprinkle the remaining taco meat and cheese over the top. Bake in the oven for about 5-10 minutes, until the cheese has melted and everything is warmed through.
