While it's a chore for some, cooking at a campsite is one of my favorite things to do. Doing so with a two-burner stove will drastically improve how easy it is to cook, and using a stove like the Classic Propane Stove from Coleman is one of the best ways to do it.
It runs off the tiny green cylinders (though you can buy a hose adapter for 20-pound tanks) which supplies two burners with individual control knobs. There are flaps to protect the burners from wind and, when you're done cooking, everything folds up neatly into its clamshell design.
The Coleman Classic Propane Stove is normally around $43 on Amazon, but it's currently just $34.30.
