Ritz crackers are popular espcially if throw in a can of spray cheese but try to put the spray cheese in its own ziploc bag. It can explode, seriously not a good mess
The torengos/pringles in the can are good. Throw in those little bean dips or cheese dips salsa
Small pack flour tortillas with can chicken breasts and little spray cheese for chicken burritos
The little lunch kits of tuna/chicken are great
The little pasta bowls are good too. They can pop the top open and eat straight out or set in on a vehicle to warm it up.
The big cans of soup with pop tops are good also.
If you need more suggestions just let me know. I have done this a time or 12. Thank you for caring enough to send a box.
