I just made a huge batch of homemade meatballs and put them in a ziplock bag in the freezer. My thought is to put them in a small crock pot I take along with some sauce and start to heat it when we arrive and set up. After a few cocktails and cheese and crackers I figure they'll be ready for subs whenever anyone wants one. At least that is the plan for this trip with 6 of us.
Seeing that I go out before my DW joins me, She usually brings out subs from a local deli. It's the easiest thing for us. If I'm alone however, I usually make hot dogs with chips. I know it's not very healthy but it's the easiest thing after setting up. The rest of the meals are will planned and better in context.
Old Boy Scout favourite... Walking Tacos. We precook the meat at home, arrive at the campground, heat and serve. Great because it leaves you with one pot and some spoons for your dishes on the first night.
For those not familiar.... You add you Taco meat and whatever fixings you want to Doritos. You buy the small bags, crunch up the chips and add the ingregients to the bag. No plates required. I would like to claim the kids love it... But I do an annual trip with six grown men and they demand this as the Friday meal every year.
You owe me a keyboard. I'll never get all the drool out of this one.
