Dice tomatoes (you want them to be nice and soft so they go a little saucy when mixed with other ingredients).
Mix them together with red onion, fresh coriander, lime juice, a little olive oil, plenty of salt and pepper and, of course, a finely chopped fresh chilli. Add as much or as little chilli as you like, depending on the type of chilli and your tolerance.
Let the mixture meld together for half an hour or so and then serve with corn chips or on burritos.
