I use them a lot but I just eat and buy only the main entrees. Just as good cold as hot. I supplement my meal with nuts, dried fruit(apricots, raisins, apples, banana chips, etc). ClifBar or granola bars are usually in my pack too.
I bought lots of them a few years ago for $1 each. The Army Surplus store here in IF sells complete MRE's and entrees only. The entrees are like $2.50. I could get some for you and bring them over if you want but our time is getting short!!!
