What did the Pioneers Eat?

Thats the big question at dinner tonight. We decided we had no idea what pioneers at on the trail and we need to do some research. Every time Aaron got a chance to talk he said "HOTDOGS!" Aaron was sure they ate hotdogs. We kept giving him reasons why they didn't have hotdogs on the trail. My third reason why they didn't have them was "They didn't have refridgerators. Where would they put the hot dogs?" and to that he answered "IN A BUN!"
