I just thought I would add a little about the food I take. I think I am a little extravagant on the food... but maybe someone here will see something they like.
Breakfast:
I usually eat quaker instant oats. With the variety of flavors (apples & cinnamon, maple & brown sugar, peaches & cream, etc.) I don't get tired of them. I also have a hot cocoa as I'm not a coffee drinker. Breakfast bars could add more variety if you don't like oats. Oats really stick with me as they are a slow digesting carb.
Lunch: I love Peanut Butter, bacon and honey on tortilla shells. I use tyson pre-cooked bacon and make up my sandwiches ahead of time, sealing them in plastic wrap or in a zip-lock bag. Sometimes I do like you Gil and just have a Pure Protein bar and some jerky or trail mix. Oberto's BBQ Pork jerky from Sam's Club is the best, tenderest and tastiest jerky that I have found. If I'm real hungry and the hunting is slow during the day... I may have a hot meal. Either a MH or Ramen Noodles with chicken or tuna added. The Ramen Noodles are bad for you (very high sodium) so I use 1/2 of a flavor packet and then add tyson chicken (from the foil pack).
Suppers:
I usually have a MH meal and like most all their entrees. Sometimes I'll switch out and have the Ramen noodles with chicken or tuna. I'll also have Instant Potatoes at times. Those come in several varieties such as; buttery, garlic, and loaded.
Snacks:
Jerky (Oberto's BBQ Pork), trail mix (my own mix of peanuts, cashews, almonds, sunflower nuts and Reeses pieces), Pure Protein bars, Nature Valley protein bars, etc.
I rebag my MH meals in a 1 quart double lock zip lock bag (along with the preservation pack) and mark what entree it is. Then I take in a couple of the original mylar MH packages to use as "bowls". I also use the freezer bag inside the MH mylar bag for my ramen noodles and chicken.
Maybe I'm too organized, but I also like to bag each days food (Breakfast, lunch, snacks and supper) in a 1 gallon double lock zip-lock bag. The one in the pic below weighs about 1.2 lbs. That way I can just throw in my backpack the number of days I'm staying out and I'm ready to go.
By the way. I park my camper near the TH and make 2 or 3 trips into a "basecamp" and stash my food and gear. I put the food in bags suspended between trees and about 10' off the ground. Once my "basecamp" is stocked... I hunt from there on 2-5 day bivy hunts. If/When the basecamp gets low on food, I hike back out and resupply.
I'm retired and basically take the whole season off.
Pics coming up of some of the food... including a "one day of meals bag"... (hanging on the bow rack).
