Instructions
Season the Steak
Toss sliced flank steak with fajita seasoning and 1 tablespoon avocado oil until evenly coated. Slicing thin against the grain is critical for tender steak that cooks fast.
Sear the Steak
Heat a large cast iron skillet or wok over the highest heat possible. Add steak in a single layer and sear for 2 minutes without stirring, then toss and cook 1 more minute. Remove steak and set aside.
Cook the Peppers and Onion
Add remaining avocado oil to the same hot pan. Add peppers and onion and cook over high heat for 4 to 5 minutes, tossing frequently, until lightly charred and just tender.
Combine and Serve
Return steak to the pan with the peppers and toss together for 30 seconds to combine all the flavors. Serve immediately in warm tortillas with your favorite toppings.
