Brown ground beef and drain, making sure it is crumbled well. Add in taco seasonings according to directions on packets.
4
Spray 9x13 baking pan with cooking spray.
5
Lay down 2 tortillas to cover bottom of pan. You may have to rip them to make them fit.
6
Add a layer of ground beef and then a handful (or more if you choose) of shredded cheese onto meat.
7
Add a layer of crushed dorito's onto cheese.
8
Repeat until you reach the top of the baking dish, ending with a layer of chips. Depending on how big my chunks of meat are, I can get 2 or 3 layers into a baking dish.
9
Cover with foil and bake at 350 for 20-30 minutes, or until cheese is bubbly.
10
Remove from oven and let sit 5 minutes. Warm refried beans and spread on top of "casserole."
11
Finish by spreading sour cream, salsa, shredded lettuce and whatever other toppings you like onto the dish.
12
I always like to garnish is with a light layer of chips onto the top of it after I am done layering.

Note: Cheese and chip amounts are estimates. I usually end up using 2 bags of cheese, but it really is in how much you put into each layer. The same applies with the chips.
