Depends on your definition of cooking. My “lazy and unpretentious” meal is pasta with whatever. If I have a pre made sauce, that. Perhaps some frozen cream spinach, that works too. A couple eggs mixed into the hot, strained noodles is pretty tasty too. If my stash is completely empty, a piece of butter. Then top it all off with some grated parmesan, and eat it quick before the shame sets in.

Edit: works just as well with rice
