put them in batches into your food processor and make yourself some pasta sauce. when you are done processing them add some garlic, fresh or dried basil, and few diced onions, a few tablespoons of sugar and cook them over medium high heat for a few hours until it thickens up a bit. when it cools down place it in zip lot bags and freeze.
i have the complete recipe in my wife's cookbook. if you are interested let me know and i will send it to you.
