I'm with Andy. I use a seal-a-meal, load the bag with some good juicy stuff, freeze it enough to do a dry seal, freeze it hard for a couple of days or weeks, and then throw it in a real cold yeti.
I do all my food in an assembly line over an hour or so. I did some tamales in early May, had them in the cooler for two weeks, got home with them still frozen, put them in the fridge for a week, finally microwaved them, and they were still good three weeks after I sealed them. The bags that you get at costco can be boiled. I use the water from boiling the bag for dish cleanup. The trash is a bag about the size of a ziplock.
I've also seal-a-mealed fresh stuff like spinach salads. Leaves get a little crushed but it keeps it all fresh and clean and hassle free.
