Yum, I wish I had a big bowl like this in my fridge now. But unfortunately I don't :( Time to make some tomorrow maybe?
Lots of tomatoes
Lots of fresh coriander
White wine vinegar
1 small onion or some spring onions, finely chopped
You could also add: sun dried tomato paste, chopped chilies, different herbs (basil is good!)
Chop all the tomatoes in half and squeeze out all the water and pips as best as you can. Then chop them all up quite finely. Put them in a bowl with finely chopped coriander, crushed garlic, and salt, pepper, lemon, vinegar and olive oil to taste.
I find this is best left in the fridge for a couple of hours before eating (if you can resist) to let the flavours blend. Seriously, it makes it better.
