We use one of the small portable two burner propane grills that we purchased years ago. It is stainless steel and uses the small green propane bottles and has plenty of room for two large steaks or several burgers for the two of us. When done it folds up and easily fits in the basement compartment. The propane bottles are available at any Walmart and the entire grill is available from several manufacturers for less than $100. The burners put out enough heat to make our useable even at high altitude in the Western mountains.
