Tomato Paste

How many of you buy those little cans of tomato paste just because you need a tablespoon of it and end up throwing the remainder away? I guess you could buy those over priced tubes...but why? Take the leftover paste out of the can and wrap it up in some cellophane and toss it in the freezer. When you need some, take it out and chop off a hunk and toss it in your pan. Viola! easy and money saved!
