The better the tomatoes the better the salsa as someone probably said at some time. It holds some truth though. Be sure to pick some good quality tomatoes (preferably organic) that pack a lot of flavours.
Chop the tomatoes, onions and garlic into small cubes or dices.
Chop the chilli. Keep as much of the seeds and the “meaty” inside as you see fit to get the amount of spiciness you want.
Fry the onions, garlic, chilli and coriander until the onions are soft and translucent.
Add the tomatoes and let simmer for a while until the tomatoes are turning soft.
Add the agave syrup, and let simmer until the tomatoes are almost completely dissolved.
Add salt & pepper to taste.
