Step-by-Step Instructions
Step 1: Prepare the Steak
-
Slice the steak into thin strips, about ¼-inch thick.

In a large mixing bowl, combine sliced steak, bell peppers, and onions.

Toss until evenly coated.

Air fry at 400°F for 10-12 minutes, shaking the basket halfway through for even cooking.

While the fajitas cook, warm tortillas in a dry skillet for 30 seconds per side.

Keep them warm by wrapping them in a clean kitchen towel.
