"Create a simple Argentinian-style scrambled eggs recipe for a household of 4. Make it cost-conscious, flavorful, and easy enough for an advanced home cook in about 30 minutes. Use metric units only. Include an air fryer option only if helpful, but keep the recipe simple. Avoid shellfish, turkey, and kale. Use common ingredients and straightforward steps. Give it an Argentinian feel, possibly with onion, tomato, herbs, or a little chimichurri-style seasoning, but keep it practical and simple."
