Quesadilla de Churrasco (Arrachera - Skirt Steak)
skirt steak, cut into small pieces and seasoned to taste. I seasoned the steak with salt, pepper, oregano, garlic powder, and a little white vinegar. I let it marinate for 1 hour • extra virgin olive oil • Onion, to taste • large flour tortilla (burrito size) • Shredded cheese (I used a mix of mozzarella, Monterey Jack, and asadero) • Butter
