I was in town today and saw a tremendous gadget in a shop. The "George Forman lean mean fat reducing grilling machine" Electric BBQ. If you have a power supply this could be the answer.
Actually, I was surprised when I first saw the box, as the word "reducing" is at 90 degree angle to the rest of the scrip and I couldn't read it. To me it read: "lean mean fat grilling machine and I wondered who would want to eat grilled fat? Then I remembered:
Mmmmmm....... Grilled fat!

Note to Nordic and Gibberish. The shop was TJs in Crawley Martletts. They've got excellent big gazebos with sides at £50 and those excellent fold down carryable camping chairs at £7.
Mmmmm.... More grilled fat.
