A smooth style peanut butter prepared by grinding roasted peanuts in convenient packets that travel well. If you plan to have sandwiches on your trip have them within the first few days. Bread is bulky and hard to pack without crushing and it doesn't stay fresh long. Pita is a good choice as it is flat and packable.
Two packets makes a good thick sandwich, so 4 packets for a couple of sandwiches should give you a hearty lunch.
Peanut butter: roasted peanuts, sugar, hydrogenated vegetable oil (rapeseed, cottonseed and/or soybean oils), salt. grape jelly:concord grapes, corn syrup, high fructose corn syrup, fruit pectin, citric acid, sodium citrate (used as needed).
Shelf Life: 365 days at 21° C. ( 70° F. ) Store in a cool place to extend shelf life.
