Cheeseburger Tacos

There is a restaurant in my building called Tin Star, and they make the yummiest Cheeseburger Tacos. I eat mine with a side of tortilla soup (instead of the fries that usually come with it) and chips/salsa. Yummy, and surprisingly easy to duplicate.

4 Hamburger patties, cooked
8 flour tortillas
Tomatoes, sliced
Purple onion, sliced
8 Cheddar cheese slices
Mustard and mayonnaise

Assemble with a flour tortilla, 1/2 a hamburger patty, slice of cheese, tomatoes and onion, mustard and mayonnaise. I think they add seasoned salt, too, which tastes great if you have it. You can also add lettuce if you want.
