Whoa..... all of the above ideas are great for a day hike or overnighter but seven days? You have the right idea serafin, a better variety is necessary. I usually alternate breakfasts with your oatmeal and freeze dried. ( I prefer Mt House Scrabbled eggs with Ham. The eggs and bacon have the eggs and a few little specks in the bottom they call the bacon, but the eggs and ham have a LOT of ham as well as some peppers etc to spice it up.) I usually plan 3-4 packets of oatmeal per meal and then just use what my appetite says is enough, usually two packets. I also plan 2 out of 3 main evening meals for freeze dried alternating with ramen for the 3rd. I still buy the serving for two packets but split it between two meals. I also carry 3 or 4 extra ramens as just in cases. I love Mt houses' Chicken Polynesian and Sweet and Sour Pork entrees. Friends prefer some of the other menus. For lunches, flat breads, flour torts, pita breads etc coupled with premixed chicken salad, tuna salad, ham salad (bumblebee makes these in little sets with crackers but they need a little more bread for me) I also break down a large bag of trail mix into the snack size ziplocks, one for each day for trail snacking. I usually throw in a couple of energy bars for day hiking, prefering snickers marathon flavors. For beverages, the gatorade packets work well as well as wal-marts GV drink packets. I also throw in several cocoa packets, preferring two packets in a 16 oz mix. Following this general menu plan, My typical food sack for 10 days including cook kit, stove and 2 fuel cannisters will be around 15 lbs, and usually have enough left over for an emergency day or two. For me, MRE's are way too heavy for any long hike. The commercial freeze dried meals also have way more flavor as well as more calories. If you are a coffee or tea drinker, the singles work well as well as freeze dried.
