Hormel® Pepperoni is a fantastic backpacking food for those who eat meat as it is very shelf stable.
It comes in 3.5 ounce packages that have two sleeves of slices. While normally sold in the refrigerated deli meat section next to the bacon, deli meats and hot dogs it doesn’t need to be refrigerated until after opening. (Marked in small words at top that most people miss) Each sleeve is perfect for one meal.
We have used it in many recipes:
Pizza Pan Biscuits (these were very good!)
Awhile back I saw another version of their pepperoni but had forgotten to mention it. It is the Hormel® Natural Choice® line (of which their deli meat is quite tasty).
The pepperoni isn’t the easiest to find, but I have found it often at higher end grocery stores. Look in the same area as the regular version. The natural line avoids adding in Nitrites and Nitrates. Personally I find the pepperoni has a cleaner flavor and is more enjoyable and is worth hunting down. The price is comparable, as is the size of the package. It is also shelf stable.
