Blend until smooth with a few chunks in it (or until desired consistency).
Pour in to a pan and simmer for 3-4 minutes and then cool before serving.
Notes
You don't have to heat the salsa, and you can just serve it straight away. But it does make it juicier and make it a nicer red colour.
You can experiment with this salsa to adapt it to your own tastes. If you want less heat, use less chilli. If you don't love coriander, use less or leave it out. Want it more zesty? Add more lime!
Serve with burritos, tacos, on eggs or as a salad dressing.
