I love Vienna Sausages!
IMO, the Hormel brand is better than Armour, though. Slice them lengthwise and put 'em between two pieces of toast with a little mayo (I prefer Miracle Whip), garlic/herb seasoning and some lettuce. Or slice them crosswise into "pennies" and have them with cheese and crackers. Right out of the can is good too for a quick midday snack.
Lots of protein but aside from that, not all that good for you (fat, sodium). But they sure are tasty when a feller is rumbly in the tummy.
Vienna Sausages are really good heated up. Just roll them around in a medium hot skillet, don't microwave them!
Oh, and as for the topic of the thread, I bought some MREs a few years back to eat while on all-day deer hunts. My favorite entree was some kind of smoked pork chop. Maybe I was starving or something, but I remember it tasting absolutely great while I sat in the hayfield soaking up the October sun.
Some of the entrees (chicken and rice comes to mind immediately) are just not that great, but all are edible and none are repulsively bad. The ingredients are good quality, but there's either too much or not enough of the wrong seasonings in some of them. Things like rice and noodles are slightly undercooked so they don't turn to mush if heated in the field (which I never did, I ate them all cold). Come to think of it, I finished two cases of 12 meals, so they couldn't have been too bad overall.
My favorite dessert was the delectable "Oatmeal Cookie-Chocolate Covered". The "Snack Bread-Fortified" was kind of nasty, but again, edible. It must have been overrun or leftovers from humanitarian aid or relief programs, because it read "A Food Gift from the People of the United States of America" on the pouch. It looked like a big, puffed up Ritz cracker but had a soft, pliable texture. It was kind of dry and was like eating slightly sweetened cardboard. It made a passable "stick to your ribs" vehicle for the jelly or cheese spread though.
All in all, in a pinch MREs are the way to go for hassle-free emergency dining; but there are better tasting options like the Mountain House line of freeze-dried foods. They're pricey but of high quality Freeze-dried ice cream is great right out of the package. Eat it slowly and let it melt in your mouth...it's as creamy and rich as the normal style.
Going the variety-of-canned-foods route is less expensive but you get foods you already know and enjoy. A lot of stuff can be eaten right out of the can, too.
