Most of the time, I eat rather unglamorous food. I don't like spending a lot of time cooking if I'm the only eater, so if it's just me, I tend to just throw together stuff in my fridge. Mexi Mash is one of my favorites since it's basically embracing the concept, "Here, let me just fancy up some basic food with SALSA!!!"
Random tangent: I come from a long line of salsa users. My great-grandmother used to pack a jar of Pace in the crocheted basket on her walker whenever she went down to meals at her retirement home. She passed down her love of the zesty.
Back to Mexi Mash.
Combine several of the following ingredients in a bowl. Top with cheese or salsa or whatever (here's a recipe for homemade salsa). Heat & eat.
Rice (my fav: microwaveable brown rice)
Beans (my fav: refried black beans)
Ground meat (for fancier, make it with taco seasoning)
