Trim any excess fat from the flank steak and slice it into thin strips, about 1/4 inch thick, against the grain for maximum tenderness.
In a medium mixing bowl, whisk together 2 tablespoons of the avocado oil, lime juice, cumin, chili powder, smoked paprika, garlic powder, onion powder, salt, and black pepper to create a marinade.
Add the steak strips to the marinade, toss to coat thoroughly, cover, and refrigerate for at least 15 minutes or up to 2 hours if you have the time.
While the steak is marinating, slice the red, green, and yellow bell peppers into thin strips. Slice the red onion thinly as well.
Heat the remaining 1 tablespoon of avocado oil in a large skillet or cast-iron pan over medium-high heat.
Add the bell peppers and onion to the skillet. Sauté for 6-8 minutes, stirring occasionally, until the vegetables are tender and slightly charred in spots. Transfer the cooked vegetables to a plate and set aside.
In the same skillet, add the marinated steak strips in a single layer. Cook for 2-3 minutes on each side, or until seared and cooked to your preferred doneness.
Return the cooked vegetables to the skillet with the steak. Toss everything together and heat for 1-2 minutes to combine the flavors.
Garnish with freshly chopped cilantro before serving.
Serve the steak fajitas over cauliflower rice for a Whole30-compliant base, or enjoy them as is with your favorite compliant toppings.
