@PNS I can't imagine ever using those products. But apparently lots of people find them useful for the price.
I just fry a hamburger/egg and/or veggies. Faster than placing an order and waiting for it, including cleanup.
I do buy true convenience foods, e.g. sliced bread, preformed hamburgers (messy and time consuming to pat 'em by hand unless you're doing the whole family - which I used to do), ready to cook frozen vegetables.
