I do something similar as what has alraedy been posted. I peel them then buzz them in a food processor...I then dump each batch into a large bowl until I am done (or the bowl is full) Then I use a big soup ladle to measure out ~ 2cups into a zip lock bag, then I add in some fresh basil, oregano, or parsley.

Then when I am ready to make sauce I just saute some garlic in olive oil and dump the bag in.

ALSO if you have alot of green tomatos at the end of the summer I will post a link to a thread talking about what to do with them.
