Set the Instant Pot to SAUTÉ. Add the oil then the onion and sauté for three to five minutes. Add all the other ingredients then set to PRESSURE for one minute. Quick Pressure Release at the end of cooking.

Blend using a stick blender or food processor once cooled a little. Put back into the pot on SAUTÉ if you wish to reheat before serving.

Season to taste with salt and pepper and serve with a drizzle of extra virgin olive oil and mint leaves to garnish, if liked.
