I try to come up with easy stuff, and some things that can be made before a trip... Chili is #1 I make prior since it is always better heated up. Pulled pork sandwiches are always yummy. I also do stuff so DH can share the duties, and he loves grilling. Burgers, BBQ Chicken. I make stir fry, breakfast on the grill, fish in foil, steak, baked potatoes zapped and then grilled. Lots of comfort food. Food just seems to taste better away from home. Sorry nothing spectacular on our menu but we like simple foods.
Very curious for other responses... Always looking for new ideas.
