I've done deliveries at night with crew who helped when it was cold. It's amazing how hot Chef Boy RD pasta from the can tastes like a gourmet meal. Easy to cook on the grill top in a sauce pan. Italian bread buttered and warmed in the grill in aluminum foil make it a real treat.
I've also done beanie weanies from the can. Again, if it's hot, and the weather is cold, everyone loves the taste!
I have an 9 cup aluminum percolator I can put on the cook top to make real coffee. Buy the coffee in the filter bags and cleanup is a snap.
Walmart has these coffee pots online.
