Ingredients

Scale
  • 1 lb flank steak or skirt steak
  • 2 tbsp olive oil (divided, for marinade and cooking)
  • 2 cloves garlic, minced
  • 1 tsp ground cumin
  • 1 tsp smoked paprika
  • ½ tsp chili powder
  • Juice of 1 lime
  • Salt and black pepper, to taste
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 medium yellow onion, thinly sliced
  • 1 tbsp olive oil (for sautéing)
  • Salt and pepper, to taste
  • 4 cups cauliflower rice (about 400g)
  • 1 tbsp butter or olive oil (for flavor)
  • Salt and pepper, to taste
  • Fresh cilantro, chopped (optional garnish)
  • Sliced avocado or guacamole (optional garnish)
  • Fresh lime wedges (optional garnish)
  • Jalapeño slices (optional garnish)
  • Shredded cheese (cheddar or Monterey Jack, optional garnish)

Instructions

  1. In a mixing bowl, combine 1 tbsp olive oil, minced garlic, ground cumin, smoked paprika, chili powder, lime juice, salt, and pepper. Add the flank steak and coat evenly with the marinade. Cover and let it rest at room temperature for 30 minutes or refrigerate up to 2 hours.
  2. While the steak marinates, slice the red and green bell peppers and onion into thin strips.
  3. Heat a large cast iron skillet over medium-high heat until very hot. Add 1 tbsp olive oil, then carefully lay the steak in the pan. Sear for 3-4 minutes per side for medium-rare (internal temp around 130°F), or longer if preferred. Transfer steak to a plate and let rest for 5 minutes before slicing thinly against the grain.
  4. In the same skillet, add more olive oil if needed. Toss in the sliced peppers and onions, season with salt and pepper. Stir occasionally until tender and slightly caramelized, about 8-10 minutes.
  5. Heat butter or olive oil in a medium skillet over medium heat. Add cauliflower rice and sauté for 5-7 minutes until tender but not mushy. Season with salt and pepper.
  6. Assemble the bowl by placing a generous scoop of cauliflower rice, layering sautéed peppers and onions, then topping with sliced steak. Garnish with chopped cilantro, sliced avocado, fresh lime, jalapeño slices, and shredded cheese if desired.

Notes

Let the steak rest after cooking to lock in juices. Avoid crowding the pan when sautéing veggies to ensure caramelization. Pulse cauliflower florets yourself for better texture if making cauliflower rice at home. Store components separately for meal prep and reheat gently on stovetop to maintain texture.
