Preheat the grill to medium-high heat.
Slice the bell peppers and onions. Toss them in olive oil and season with salt and pepper.
Grill the steak for 4-6 minutes per side, depending on thickness and desired doneness.
At the same time, grill the peppers and onions in a grill basket or directly on the grates until tender and charred.
Let the steak rest for 5 minutes, then slice it thinly against the grain.
Warm the tortillas on the grill for about 30 seconds per side.
Assemble the fajitas with steak, peppers, onions, and desired toppings.
