"Create a simple chimichurri pork recipe for a household of 4. Make it cost-conscious, flavorful, and easy enough for an advanced home cook in about 30–60 minutes. Use metric units only. Include an air fryer option for the pork if helpful, but keep the recipe simple. Avoid shellfish, turkey, and kale. Use common ingredients and straightforward steps. Keep the chimichurri bright and herb-forward, and use pork chops, pork tenderloin, or pork loin as appropriate."
