Pan-Cooking

1. Sprinkle the steak on both sides with salt, pepper and hot spices, as well as a drizzle of lime juice. Let the steak marinate in a glass dish for up to 1 hour, turning once or twice.

2. Put a small amount of olive oil in a heavy-bottomed skillet and turn the heat to high. When the oil has heated, put the steak in the skillet.

3. Cook the steak on both sides, about 3 to 5 minutes per side. Move the steak around the skillet as it cooks to ensure it doesn't stick to the surface.

4. Transfer the steak to a cutting board and let it rest for 5 minutes.

5. Slice the skirt steak thinly, going diagonally across the grain. Add the steak as a layer in the quesadillas.
