Most of the year it's ok to use tinned tomatoes but when in season you can't beat the taste of fresh, home grown tomatoes!
I only use chopped tomatoes as I find that the tinned whole ones you have to remove so much of the tomato stem & centre core on some makes, The Poundland shop near us is doing 12 tins for £3-00 and they are very nice I have had them on toast as well as in two recipes!............
