Welcome to DC! Are you looking for ideas for how to freeze summer or winter squash? For summer squash (zucchini) I peel it, grate it, and freeze it on a cookie sheet in 1 cup measures. I then bag the "balls" in zippies. I use these balls in soups, zucchini bread, muffins, stir fries. For winter squash, I store those in the cold storage. However, I have also cooked those, pureed them, and frozen that. I would think you could blanch chunks of it and freeze it. You could look for "how to freeze squash" and there is probably information on how to do that on the Internet.
