>>2800523For backpacking if weight is of concern it's couscous. Adding dried herbs, powdered citric acid, dried fruit and seasonings beforehand means really all you need to add is some meat for a great filling meal.
If weight is not of concern then fire baked potatoes and scarpariello.
If I'm near water with fish I'll cook what I catch, fish only really needs butter, salt and pepper.
As for protein, eggs are pretty based. If you're european the eggs aren't cleaned when you buy them other than with water, so they still have their protective coating. Don't put them in the fridge after buying (condensation fucks that coating up) and they'll easily last an entire hike without cooling. Just don't drop your bag too hard or it'll get messy. If you're american, I'm sure it'll still be fine for a few days, pat them dry after removing them from the fridge or something.
If there's something like a "signature dish" then for me it is falafel. Doesn't need cooling like most protein does and you can buy it as pre-spiced dried powder. Hydrate the powder, form into balls, cook in oil. Make a salad out of diced onion, ripe tomato, cucumber and make a sauce made of tahini, lemon juice, honey or sugar, and optionally some garlic. Wrap the freshly cooked falafel in a wheat tortilla together with the salad and sauce and enjoy.
Honorable mention to infused garlic oil ramen if I can't be bothered or for later days in a hike. Minimal additional effort and ingredients and it takes ramen, which is a pretty dissapointing hiking food imo and turns it into something really amazing in flavor.
