You can scoop cookie dough onto parchment or waxed paper, freeze and then pull of the frozen chunks and toss into a freezer bag. Then you can just make the amount that you want.
If you ever have weekend day when you're not pulled in all directions, you can make apple pies in foil pans, double wrap them in freezer (heavy duty) foil and freeze those too. Apples are just finishing here and if I have any free time, I'd do this.
Cranberries now that they're in season. Fresh berries in the summer. If your farmer's market is still going, baked/steamed or otherwise cooked winter squash in freezer bags. Freeze flat bags like a large envelope, that way they'll defrost sooner.
Flour bought on sale. Half gallons of OJ when they're on sale and not limited in number.
Stonyfield Farm Yokids yogurt tubes freeze very well. I believe I was told that they were formulated to freeze well.
Instead of freezing cut tomatoes, I just made batches and batches of sauce in my slow cooker and froze those. Next year, I'll try the cut tomatoes.
Blanched kale, mustard greens, collard greens, etc. The kids didn't really get excited by that one though.
Pesto without... the nuts, I believe. I know you can freeze the basil, olive oil and cheese mixture but not for a very long time. This year our basil did so poorly, we barely had a cup of pesto at the end of the summer.
Some people freeze fresh herbs in water, in ice cube trays and then pop them into freezer bags. Personally, we nearly always use up our herbs during the growing season and then forget the remainder. You'd have to use the frozen herbs in cooking, like soups.
Nuts! If you find a sale, or shop at Costco like I do, nuts stay fresher if frozen.
Shredded carrots freeze well if you're planning on making carrot cake or muffins with them. They'd probably be fine in a pureed soup also. Ditto for zucchini.
Menus4Moms.com has a quiche in a baggie recipe that works pretty well. You can always make double lasagna, quiche, chili and meatloaf and freeze those too.
Hope this helps,
