Chop each of the tomatoes into eighths and add to a bowl.
Add in the finely diced onion, chopped coriander and a pinch of salt.
Stir together and serve.
Can I make it ahead?Yes you can make it up to a couple of hours ahead, cover and store in the fridge. Just give it a little stir before serving. If you wanted to make it up to a day ahead, you'll notice the tomatoes will release some of their liquid, and the coriander will wilt slightly, but it will still taste great.Can I freeze it?No, I don't recommend freezing this as the tomatoes will go mushy upon defrosting.Ingredient swaps
Swap out the coriander for fresh mint, or do half mint, half coriander. You could also add fresh parsley too if you like
Swap out the onion for red onion or spring onions.
Swap out the cherry tomatoes for larger tomatoes. I'd recommend you use dark red, ripe tomatoes (ideally vine-ripened) for the best taste.
