Season both sides of the steaks with fajita seasoning and let them sit at room temperature for 20 minutes.
Preheat your grill to medium high heat. Brush the grates with olive oil to prevent sticking.
Grill the steaks until they reach desired doneness, about 4 5 minutes per side for medium rare. Remove from grill and let rest for 5 minutes. Slice into strips.
In a large skillet over medium heat, cook the bell peppers and onions with olive oil until tender. Season with salt and pepper to taste.
Assemble the fajita bowls by dividing rice or cauliflower rice, steak strips, cooked vegetables, avocado slices, cherry tomatoes, and cilantro among two bowls. Squeeze lime juice over each bowl.
Chef’s Insight
Marinate the steaks for added flavor and tenderness.
Notes
For a vegetarian option, replace beef sirloin steaks with portobello mushrooms or grilled tofu.
