This was a big hit when I taught adult ed Spanish cooking.
1Brown ground beef and dry taco mix in fry pan chopping it smaller and smaller as it cooks. (Do NOT add liquid as taco mix suggests.)
When cooked, turn up heat and brown meat a little to add flavor.

Add layer of meat
Add layer of Sauce
Add layer of cheese
3Repeat until you've used all of the ingredients.
