We love our Food Saver and use it all the time.
We use ours to marinate meals ahead of time. Take lamb chops, for instance. Lightly coat in olive oil, lemon juice, oregano, fresh garlic. Drop in a portion bag, seal it up and toss it in the freezer. When we go camping, we just pull a couple portions out of the freezer and your meat marinates while it thaws. Cut it open and toss it on the grill.
We also do a rosemary chicken that turns out great. Take some of your favorite Italian salad dressing, stir in some fresh rosemary, and then pour into an ice cube tray and freeze. It won't get a hard freeze, but will solidify enough to vacuum pack. Drop in your piece of chicken, two "cubes" of your marinade, seal it up and freeze. When you want to use it, as the chicken thaws, so does the marinade and you are ready to go in a couple hours.
You can also do the same with a pork roast. We buy a big one at Costco and cut it into individual chops, prepare a marinade and seal them up in individual portions before freezing.
We also have a big vegetable garden and vacuum seal portions of green beans, summer squash, zucchini, whatever we have. Give your veggies a quick blanch in boiling water, dry with a paper towel and then freeze on a tray. Once frozen hard, separate into portions and seal. We also whip up some herb infused butter, or whatever suits our fancy, and put a tablespoon into each pouch before sealing. Once sealed, toss it in the freezer. When you want to eat it, boil some water, drop the pouch in for a couple minutes, the veggies heat up, the butter melts and you have a great tasting, garden fresh veggie in herb butter ready to go in about 5 minutes.
When we go camping, we grab out of the freezer whatever we want, put it in the coach refrigerator for a slow thaw and have great meals on the go with virtually no work.
