If you are roasting your own capsicums, preheat the oven to 200C / 392F. Line a baking tray with baking paper.
Prepare the capsicum by removing the stem and seeds and cutting into quarters. Place on the baking tray along with the peeled garlic cloves and roast for 30 - 35 minutes until charred.
Remove to a heat proof bowl and cover with cling film until cool enough to handle. Remove skin.
Place roasted capsicum, garlic and all remaining ingredients into a food processor and blend until smooth to your liking. Taste for seasoning and add more chilli, salt and pepper as required.
Drizzle with olive oil if you like for extra added fats.
