I've been using Sainburys' 2 Minute Meals for a while now. They're actually microwave meals but the plastic seems perfect for boil in the bag too. If cooking for 2 it's worth knowing that two meals fit perfectly in an MSR kettle, and you can then use the hot water for quick-cook rice! Oh and they're cheap as chips, a fraction of the price of Wayfayrer or similar!
