This is a red version of the classic Argentinean green chimichurri sauce. It is built on the basic green sauce, but here you add paprika and peppers to the mix. It can either be hand chopped, as I do here, or you can buzz it in a blender; if you do that, this will lighten up the color considerably.
Mix the vinegar with the minced garlic, shallot, hot pepper and roasted red pepper and let this sit for 10 minutes or so to mellow out. Mix all the remaining ingredients together and let the sauce sit for at least a few minutes, or, better yet, an hour, before serving at room temperature.
