Shepherds Pie, Casseroles, Lasagne, Chilli Con Carne, BBQ lots of stuff, baked potatoes in fire or oven. Prior to boon docking, make up lots of pastry items, like Cornish Pasties, Quiches, Sausage Rolls etc that can be hand held with a serviette once made.
Basically we eat as we always do for the most part Boondocking or not, unless we are going to be boon docking in excess of 2 weeks in one place with no option to empty/refill our tanks and we can with proper management last well over 3 weeks out for 2 of us on our tanks.
