Here is what I do.
Here is some info from the Ohio University, that gives some good guidelines for freezing. They say that green onions do not freeze well, but I remember seeing on someone's blog that they sliced and froze green onions in an empty water or soda bottle, i think.
I freeze vegetables all the time. One of my favorites to freeze is bell peppers. It seems they always go bad before I can use a whole one up. So I have started to chop up bell peppers and flash freeze them, then store them in a zip loc bag. I use them mostly in soups and sauces, so I cannot vouch for how they stand up in a salad or other uncooked dish.
I also freeze fresh corn with my sister's recipe. I always have to call her for it, which I will have to do, then I will post it for you.
I think this recipe would be good with other veggies.
I make herb pestos and freeze them in ice cube trays and store in zip loc bags.
I can tomatoes usually, but when I was looking at the guide below, they say to freeze tomatoes you can stew them and then pack them in zip loc or other store containers. I like that idea.
You can make pickles and relishes with a lot of vegetables and either can them or freeze them. I have a wonderful recipe for freezer sweet and sour pickles, and I have added cabbage and red bell pepper to it and that was very good. I also have a very good recipe for dill pickles from my mom. I made 24 quarts last year and stored them in the basement (or any cool place), and we just opened the last jar. I didn't waterbath them, because my mom and sister never did and they turned out great. I used to have trouble finding dill tops in San Diego, so you would want to grow some dill if you are in an area where it might be hard to find it. Here is MO, I find them in huge bags at the market and Farmer's Market.
Okay, I will post the recipes a little later as I have obviously had too much caffeine today. I forgot to count the caffeine in the very large ice tea I drank before my coffee and now I can't stop typing. smileys/smile.gif
