A great replacement for MH is Knorr Rice/Pasta Sides.
Knorr is good, and I also like the Meijer and Kroger brand pouch rice and pasta, in fact, I usually buy the store brands, as they often are on sale for around $0.88. Taste wise, I can't tell a difference. I have a small plastic tote full of these things that I'm gonna keep for a few years and see how they taste after expiration, as long as bugs don't get in, I can't see them going bad.
