In a medium skillet over medium heat, break up the ground beef. Cook until cooked through, drain the excess fat from the pan, and stir in the taco seasoning.
In a small bowl whisk together the ingredients for the sauce.
Place a large skillet that you can fit with a lid over low heat.
Divide the sauce in two and spread over two of the tortillas.
Working with one tortilla at a time, spray the skillet with a very small amount of cooking spray. Place the tortilla (that has been prepared with the sauce) in the skillet. Add half the cheese and half the beef and top it with another tortilla shell.
Let it cook for about 2-3 minutes or until the shell begins to turn golden brown. Cover while it is cooking. Flip it over, recover, and cook for another 2-3 minutes. Repeat with the remaining ingredients.
Slice with a pizza cutter and enjoy.
I used light mayonnaise. It saves on the calories and doesn't change the taste.
