After preparing your green herbs, peppers, garlic, and shallot, add to the bowl of a large food processor.
Combine the red wine vinegar with the vegetables and pulse a few times to just break down the ingredients.
Next, add the olive oil and blitz the sauce until thoroughly chopped. You’ll know when you’re at the right consistency when the mixture looks like a finely chopped salsa.
Taste, and season with salt & pepper.
Transfer the sauce to a large glass bowl and allow it to sit at room temperature for 30 mins before serving. This resting time allows the flavors to meld.
Refrigerate any remaining sauce and use with in 3-5 days.
