Ripe avocado, mashed
Shredded cheese, your choice
I didn't list any amounts because it's pretty much up to you.
Preheat your broiler on high. Take a tortilla shell and gently spread the smashed avocado over it. Add the cheese. Place in the broiler and allow the cheese to melt. Watch closely...doesn't take long. Remove from oven and add chicken, salsa, lettuce and tomato and any other toppings you like. Enjoy!
