Vacuum packing food, what should I try?

just got a food saver vacuum packer thing and so far I am having a fun sucking the air out of stuff and freezing lumps of soup. but I realize there is more to cooking and freezing than that.

vacuum marinades are something I have some experience with as a place I worked had rotisserie chicken marinaded that way (divine by the way) does anyone have a good easy to make or off the shelf marinade to recommend? chicken/fish/pork/beef I will cook anything.

also anyone tried freezing meals? I cooked up a pot roast with taters, carrots, peppers, and pineapple the other day and then packaged the veggies in with thick slices of pot roast. looks great but I am not so sure how it will reheat down the road.

I was thinking of doing the same with a breakfast mix I make with veggies eggs and bacon/sausage and then having ready to eat morning food.

one thing I found works wonders with packaging soups/stews/chili is not to just freeze it first (yeah I know they point this out) but I picked up some plastic trays that are about 2" deep and maybe 1/2 inch or so narrower than the bags are. perfect for freezing single servings of liquidy stuff and they come out in bricks for easy stacking.

Whatever you do, don’t try to vacuum pack Cheetohs.

ETA: I mean, sure they’ll be flat and easy to stack. If you think that’s worth pulverized Cheetohs, well, go nuts.
