The original college casserole. Discovered on a box of Kraft Mac & Cheese and perfected in an apartment in Bloomington, IN in the mid-90's. This recipe is super cheap, healthy(ish), and delicious. Jessica hates it, yet has never tried it. Same with White Castle. I think she just hates the idea of both and I make fun of her relentlessly.
This recipe kept me alive in college when cash was exteremely low. I could easily get 2-3 meals out of this.
