To make chimichurri, simply mix red-wine vinegar, water, garlic, bay leaf, salt, dried hot red pepper flakes, and coarsely ground black pepper together. Once the salt has dissolved, mix in the olive oil. Once combined, add the parsley. Let stand in room temperature for 30 minutes. Take out the bay leaf before serving.
