Recipe of this sauce has Spanish roots, it is a bright and very tasty sauce that goes well with almost everything. In the classic version, white bread is added to the sauce to thicken it and get a pureed structure. I don't do this, firstly, it tastes better to me, secondly, it is healthier and less caloric, and thirdly, bread shortens the shelf life of the sauce. Try it, I think many will like the bright vegetable taste of this sauce with smoky notes.
