Taco Mac and Cheese
This isn't a recipe, but you can make it work.
I made mac and cheese using a roux, sort of like this recipe here.
Then I made taco filling with ground beef, according to the package directions on the taco seasoning. I used this.
Prep whatever toppings you want, we had shredded cheese, lettuce, sour cream, jalapeños, and salsa.
Assemble taco filling on top of mac and cheese, then top with whatever you like.
I plan on writing this out completely when I have more time.
