I change it up quite a bit depending on mood, but some of my favorites are:
Dinner:
-High quality Ramen with either packaged tuna or smoked oysters (not a big weight savings)
-Instant mashed potatoes and home dried pot roast
-home made dehydrated chili
-packit gormet meals (havent used hunting, but they are amazing from some i have tried camping)
-Minute rice and home made dehydrated teriyaki chicken
-Minute rice and home made dehydrated chicken curry
-Home made dehydrated pulled pork w/home made dehydrated fajita mix. Bring a couple tortillas and some salsa/hot sauce packets for pork tacos
-Add olive oil to any of the above. I usually bring a 6 oz pack for a 5 day hunt.
-All are made and put into heavy duty ziplock bags. I used to vacuum seal, but ziplocks are so much lighter and I havent had an issue yet...knock on wood. To rehydrate, I have brought one mtn house for the first meal and then used that bag, but it is kinda messy. This year I will be making my own re-heat stand up onvelope out of reflective bubble insulation.
And the best one ever, fire grilled tenderloin or grouse with seasoning rub that I never forget to pack!
Lunch: - I never did hot lunches, but here are some of my favs
-Butthole sandwiches - I do some version of them 80% of the time. May use tortillas instead of bagles or cream cheese instead of peanut butter, but basically the same.
-Greenbelly bars
-Home made deer/elk jerky and good hard cheese, sometimes add dried figs
Breakfast:
-Museli w/dried dates or figs and powdered whole milk - pack in a zip lock and just add water.
-Pakit gormet pollenta and sausage - Only tried camping, but yum!
-Packaroons from Heather's Choice - expensive, but probably the most delicious thing I have ever had on the mountain
-Greenbelly Bars
I'm sure I am forgetting some good ones, but that is a good starting point. The big weight savings is ditching the heavy bags that mtn house come in and getting more fat into your food. I used to feel like crap after 5-7 days of mtn house. Now I feel great most of the time.
