I fry up a 2-3 pounds of hamburger at the beginning of the week. (Crumbled with some chopped onion, salt & pepper, and a splash of worcestershire sauce).
I keep it in the fridge and bring containers of it to work for lunch! I reheat it in the microwave, topped with a couple slices of cheese! Yummy!
Or, add some more spices and put it on top of a salad with some shredded cheese, salsa & sour cream and call it a taco salad!
I even have it for breakfast, topped with a couple of fried eggs!
