Oh yeah. At home I try to double my meals when I cook, eat one and freeze the other. In this way we can reach into the freezer and grab foods for an impromtu or even a planned trip. Sure makes life easy. Cooking on the grill is fun but sometimes it's nice to have a lot or even most of the cooking done. For packaging, it depends on what I have available/empty. I use freezer-grade gallon Ziplock bags for some stuff. For other stuff I use the snap-lock lid plastic containers that have the silicon seal in the lid. They work well for us: they really are leak-proof and they freeze well. Value added they are various configurations of square/rectangular, which means they pack most efficiently in the fridge, in the Power Chill and even in the traditional cooler. Especially for camping with little kids, I applaud your desire to cook ahead of time. It will make your life so much easier, and your camping so much more relaxing!
