Sorry, I only have the filling, easy to eat, and no prep parts to give you. I'm no health expert, just a lazy Lemming.
Normally my daily routine is a bowl of Cereal with milk. I have a banana sometimes with it. Zero prep.
If I need to count on having energy for the whole day, it's an over easy egg on buttered toast with margarine and black pepper. Some prep required.
My unhealthy "dinner for a week" meal is a pack of Costco hotdog buns and sausages that I cook two at a time whenever I want and slap mustard on it. That's 8 or so meals for just over $20.
I could cook more and better stuff but I'm just too lazy to do the prep, the cooking and the cleanup, but I'm also too cheap to do takeout more than once a week.
