2 tablespoons grapeseed oil (or other high smoke point oil)
1 green bell pepper, sliced
1 yellow bell pepper, sliced
1 red bell pepper, sliced
1 medium yellow onion, sliced
Directions
Remove the fat cap from the steak. Slice the ribeye into ¼-inch wide slices against the grain.
In a small bowl, mix the salt, pepper, chili powder, cumin, and paprika together.
In another large bowl, combine the orange juice, cilantro, olive oil, garlic, and cornstarch until smooth.
Add the seasonings and whisk to form a marinade.
Add the steak to the marinade and toss to coat. Cover with plastic and marinate for 15 to 20 minutes.
When ready to cook, heat the grapeseed oil on a cast iron griddle or large cast iron skillet over medium heat.
Add the steak to the cast iron and begin to sear in a single layer. Add the bell peppers and onions, spreading the onions on top of the steak and the peppers on either side.
Cook, tossing often, until vegetables are soft and ribeye is nicely browned, about 8 to 10 minutes.
Serve the fajitas immediately (while still sizzling) with tortillas.
