Super lazy? Random bread/toast with store bought hummus.

A little bit cooking is okay? Then pasta with olive oil and garlic (and parmesan or chili if available). Or alternatively I put a can of kidney beans with a can of tomatoes, garlic, chili, and spices in a pot, cook it a bit, and serve with rice, pasta, bread, or tortilla chips. Or whatever else is quickly available.

Or frozen pizza.
