Well I usually get food from the store. But I think I know what you meant. Anyway at home I often pick up several days of food at the grocery with my bicycle. Both panniers are often packed full.

When I am on tour and I camp, I usually don't cook. Rather try to find a campsite near restaurants. When I credit card tour I often take the bicycle to the restaurant. Most memorable was Metaline Falls. Stayed at an awesome motel outside of town. Only restaurant was in town. Pitch black going back to the motel. All I could think of was a bear wandering out onto the road in front of me on the climb back to the motel.
