What food to take on a 3-4 day long hiking trip?
It should be easy to prepare, light and shouldn't go bad after few days in the heat. How much would it approximately weight? Lets say there won't be any grocery stores along the way (there will be, but I want to get used to this, so we can travel in more desolate places in the future).
EDIT: We were hiking before, but the food we took was not optimal (heavy, lots of snack bars) and we went to grocery stores along the way. The trip is in an area with low hills, water is not a problem. The answers do not need to be specific for this trip, just a general list of foods that are a good choice for hiking.
I also wondered if it was off-topic but after so much inconsistent closing in the past I often don't like to guess now \-:
Well, I certainly agree with 99% of these ideas. Ramen or Instant Noodles are a very good way to get a good source of food in a snap of a finger. Just get some hot water and leave it there for about 2 minutes and its all done.
A lot of what you need you can just get in the grocery store - rice, pasta, dried potatoes (either mashed or slices for "au gratin), sausage like pepperoni and salami that specifically doesn't need refrigeration, dried fruit and nuts, instant hot cereal (oatmeal, cream of wheat etc), dried legumes (especially lentils which don't need soaking) jam, honey, and peanut butter will take care of a lot of your needs. You'll want to put things into different packaging so they can survive in your pack and so that you're taking the right amount for the length of the trip.
My favourite camping breakfast is instant oatmeal. Add extra raisins, brown sugar, or other dried fruits if you like. Boil water in the morning and you have coffee and oatmeal and you are set for a pretty physical day. (Bring a whisperweight stove that uses butane or liquid fuel - fires are far too slow for morning purposes.) Beef jerky (made at home if you have a dehydrator, or bought in the store if you don't) along with dried fruit and nuts will meet any snack needs through the day. If you must have lunch, you can use bagels or English muffins (on week+ trips I make my own english muffins, your trip is short so just bring a few packages) with cheese (the "light" cheeses keep better, and buy several small ones so they stay sealed longer than one big one), sausage (the no-refrigeration needed ones), peanut butter, jam, or honey. If one of your days features a big climb to a gorgeous lookout and you know you'll want a rest, packages of soup mix from the grocery store can make a 30 minute stop into a delightful lunch. Again the whisperlight stove and some locally-sourced water.
Dinner the first night can be meat you took from your freezer that morning, wrapped in plastic and several layers of newspaper. I've done it and when we unrwap it, it's not just cold, it still has ice crystals in the middle. Fry it, and cook some fresh veg with it as you would at home. The second night try pizza in a frying pan using that no-refrigeration pepperoni, some cheese, and maybe some onions and any other veg you've brought. The third night, something vegetarian built around lentils and rice - we love kusherie - or beans in a sauce, like meatless spicy chili with dumplings. You can also dry hamburger meat (cooked) in your oven at home and use that as the meat in spaghetti sauce or shepherds pie filling. Set the hot pan of cooked sauce aside with a towel around it while you cook the starch - it will stay plenty warm and you only need the one little stove. These need you to bring canned or dried veg, I choose dried for the weight and rehydrate them right in the sauce or stew.
Bottom line is this is way easier than you think. Have a great time!
