First, eat a bunch of those tasty liquor filled dark chocolates only to collect the plastic trays bulk amounts come in. The trays are a perfect size for flattening the ziplock bags so they can be stacked effectively in the freezer. Cutup tomatoes to make the skins easy to eat, mix in fresh chopped herbs and garlic, jiggle bag and suck out air bubbles before flattening on chocolate trays. Once Bags are frozen the trays can be reused indefinately. the tomato and herbs retain the best flavor and have less nutritional loss than canning. Merely thaw out and mix in pasta without overcooking. Simple and yummiest!
