Warm weather can affect the use of dairy products described below. That said:

Salami, butter and string cheese on the big crackers like ry-krisp.

Mix peanut butter, crumbled bacon and whatever sweet syrupy thing you like, put it in the Coghlan food tube, and squeeze out a line to eat with a bite of bagel. Might need to warm it in a pocket for a bit first...

A block of cream cheese to be chunked onto whole wheat/cinnamon/raisin bagels...

Logan bread - search here for recipes, soak the grains first, and aim low on qty of baking powder...

I eat cold food and don't bring a stove unless game size dictates the packout will be more than one trip, or if I have the kids with.
