Everything you need
Preheat your oven 450
Get a casserole pan and lay out the Doritos in it. I cover up the bottom of the pan then kinda of break them
Put a layer of cheese on the Doritos so they stick together after the cheese melts. I like LOTS of cheese on mine! But if you aren't a cheese person then you don't have to put a lot
Brown your ground beef. Drain it. Then cook beef and taco seasoning as directed on back of the seasoning pack I like Ol paso hot and spicy but you can use whatever you want
After it's cooked spread evenly over Doritos
Add more cheese! or not!
Cut up your tomato
Break off some lettuce
And put in the oven for 5 or 10 minutes or until cheese is melted and everything is warm! Enjoy!
