I just got one of these and I must say that I wish that I had some way of getting some more of them. There are 18 servings in this one heavy MRE polytray!! I have the Mashed Potatoes with Chicken Breast in gravy. Great deal on some MREs to put back for the whole family. I am not sure how it would do in a Bug Out bag - it does weigh a bit. But it would do good in your house food storage or in the back of your bug out vehicle. Pepperoni Pizza MREs sounds like something to have on hand also. Kids would love them.
You warm them up the same way as you can a smaller MRE - just boil some water in a big pot and put this in it for a few minutes.
