Put the frying pan on to high heat and when it is very hot put all the vegetables on it, except the chillies.No need for oil, as we want to toast them.
Make sure to turn the vegetables around when you see black spots. When all the vegetables are ready put them aside, making sure peeling the garlic. Then start toasting the chillies for a few seconds, they will toast almost straight way, specially if your pan is very hot.
Put everything in a pestle and mortar or in a blender, add salt to taste and mash or blend until getting a nice runny consistency.
