I gota 6 pound can of chopped tomatoes for pizza a few weeks ago. I opened it last week. Well,I have only used about one pound. I was figuring on freezing it today or tomorrow. I talked to a guy I knew who does catering who told me it cannot be freezed after this time in the refrigerator, but should be freezed immediately after opening the can.
So I asked him how long they are good just in the refirigerator and he said about two weeks.
The only size I can get these tomatoes are 6 pounds, They are not available in grocery stores, but in a restaurant supply store.
