And here are my own personal opinions of various MRE entrees:

Ham Slices - very good, like Hormel Tender Chunk Ham. Goes good mixed with potatoes au gratin.
Beef w/ Mushrooms - excellent - good mixed with rice
Beef Ravioli in Meat Sauce - ok, a little dry, small ravioli
Beefsteak - not bad, meat patty, tasty by itself, better on bread with cheese
Beef Stew
Cheese Tortellini - excellent veggie entree
Chicken & Rice - very good
Chicken Breast Fillets
Chicken Breast with Cavatelli - one of my favorites, good hot or cold
Chicken, Noodles & Vegetables - ok entree, like chicken and rice but with noodles
Chicken Stew
Chili & Macaroni - very good, tasty
Corned Beef Hash - even a 10 year old entree was still good
Escalloped Potatoes w/ Ham - good, a 10 year old entree was still tasty
