Potatoes are another side dish vegetable that freezes well. Just wash and peel potatoes. Then cut into pieces and drop into hot water. Boil the water and potatoes until the potatoes are soft. Drain the water off and mash the potatoes. Add in butter and let it melt into the potatoes.
Once the potatoes cool off a bit, scoop them into freezer bags. Make sure you scoop enough into each bag for one meal. Label, and flatten the potatoes in the bag so they will freeze flat in the freezer.
