Make & freeze meatballs....with or without sauce. Subs,pasta,veggies etc all go good with. I always took hard boiled eggs.Eat as wanted,chopped in salad or egg salad.Frozen baggies of veggies you use are easy to tote & use.Thin buns ....easy to pack & lasts longer than regular buns/bread.Sloppy joes,also froze at home. Cooked ground meat of your choice is great.Add to gravy,serve over baked potatoes or rice,loose meat sandwiches on thin buns.Make a huge bag....or 2 of cut up,ready to go veggies. Pasta salad,any salad ....or just cook in main dish or use as "make your own salads". Bean soup freezes well,beanie weenie,or brats n beans.You can never have too many potatoes cooked & chunked.
This post brought back memories.These days,old bones prefer the easy life...lol.Have a great trip.
