No, I meant more* tasty* that C-Rats.
Are your MREs in a dark brown package or a light brown package? Light brown ones are newer and IMHO much better. The newer ones do have nutritional information and ingredients on them but they are inside the individual packages, usually on the cardboard around the main course.
And for god’s sake don’t eat them cold if you can help it. MREs have had heater packets in thm for several years now.
You can also try Canadian IMPs. Same sort of thing, but different. I like them better than MREs, myself.
As for heating the rations, if you don’t have the heaters, you can put the pouch in hot water, lash it to the exhaust manifold of your car while driving, etc.
