So I made this out of leftovers and my kids tore it up! 
I guess you can call it Taco Rice Bake? 
It was pretty tasty and really easy.
**I had leftovers in my fridge, so the amounts may vary and may not be exact **
* About 1lb or 2 of taco meat filling
* about 2-3 cups of cooked white rice
* about half cup to a cup of taco sauce
* shredded sharp cheddar about 3 cups
* about 6-8 crushed taco shells
Warm up your taco meat and taco sauce in large skillet. When heated thru, add cooked rice and mix well. Transfer mixture to baking pan, and add about 2 cups of cheese and mix. Top with more cheese, crushed taco shells and more cheese. Bake at 375 for about 15 min or till chips are crispy & cheese is melted
