Chimichurri Toss all ingredients into a food processor or blender. Pulse 8-10 times until herbs and alliums are finely diced and all ingredients are incorporated. Alternatively, finely mince the parsley, cilantro, oregano, garlic, shallot, and jalapeño. Place minced ingredients into a lidded jar and add the vinegar, oil, lemon juice, red pepper flakes, salt and pepper. Shake vigorously until combined. Keeps chilled for about a day.
