I have had Italian, French, and British versions of MREs. With each of these, you only received one box, or meal set, for the entire day, and there wasnt much in them. They certainly did not equal three of our MREs for a day. You could eat the whole darn thing at once, or ration yourself for the day.
The French one contained many tins of food, not baggies, and their variety was awesome. I had rabbit, duck, some sort of horse meat, and some others that I found interesting.
The Italian one was pretty bland, but it did contain a small shot size bottle of the worst rot gun alcohol I have ever tasted. It also contained very little to tide you over for a day.
The best by far was the British meals. These, however, required you do do some cooking, as the rice was raw and you had to boil it if you wanted to eat it. The one I had contained a fairly large tin of beef stew, and was absolutely delicious. It also had a large tin of cured bacon, about six inches in diameter. It was like the took a strip of bacon and rolled it, then rolled it onto another, and kept going until you had this massive amount of bacon and then stuffed it into the tin. It was some of the best bacon I have ever had. It also contained some of the best tea I have ever had also, very strong but not bitter. Go figure.
Overall, I found the French MREs to have the greatest variety, but if you were to survive on one meal set per day, you would be pretty hungry at the end of the day.
