I buy the big tin of MH chicken and add the gainz to my meals. Like you I eat a certain way to keep the gains goblins on trail at bay.
My go-to is Annie's Mac & Cheese + chicken + seasonings (taco is a fine start) + powdered butter depending on calorie goals. Easy 800-1000 calories and 60+ g protein. I aim for a little more than you but it's easy to adjust the recipe. Another favorite of mine is honey + Sriracha + chicken + couscous. Adjust for macro needs as well. Couscous = underrated.
What carb sources can you handle? I can help you build out a macro based backpacking plan if you are a little more specific!
Some of the freeze dried meals from REI really aren't too bad! I want to get a dehydrator one of these days but until that happens I tend to rely on those. The Thai style noodles from AlpineAire are my favorite!
They are pretty high in protein, but still carby too. To make up for it I usually pack edamame, jerky, and nut butters to even it out. (Though I always have to remind myself that while backpacking carbs are also necessary).
They also have dehydrated soups and such at Whole Foods which you could check out! Or you could look into bulk freeze dried chicken on Amazon. I've been meaning to buy this and add the soup mixes/other freeze dried veggies to my own freezer bags and see how those work.
Lastly, I totally get you. When I come back from trips (Going backpacking this weekend actually) all I want to eat are carbs.. But either way, have a good trip!
