I use it occasionally - I do not use tomato sauce often however I always have some in the fridge.
Sometimes I have it when I make a pie, and usually the second day I may put tomato sauce on it.
I very occasionally put it in cooking - if I have no tomato paste, or if the recipe calls for other tomato products that I do not have.
I also use it when my grandson comes over, but still only occasionally.
It is a "must have" product that I keep but do not use often!
