Ingredients

Scale
  • 1 lb (450g) flank steak or sirloin, thinly sliced against the grain
  • 2 tablespoons olive oil (for sautéing and marinade)
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon garlic powder
  • Salt and freshly ground black pepper, to taste
  • Juice of 1 lime (for marinade and finishing)
  • 1 large red bell pepper, thinly sliced
  • 1 large green bell pepper, thinly sliced
  • 1 medium yellow onion, thinly sliced
  • 1 teaspoon olive oil (to sauté veggies)
  • 1 medium head of cauliflower, riced (about 4 cups/300g pre-packaged riced cauliflower)
  • 1 tablespoon olive oil or avocado oil
  • Salt and pepper, to taste
  • Optional: 1 clove garlic, minced
  • Optional toppings: fresh cilantro leaves, sliced avocado or guacamole, Greek yogurt or sour cream, fresh lime wedges, jalapeño slices

Instructions

  1. Prepare the beef marinade: In a medium bowl, mix olive oil, lime juice, cumin, smoked paprika, chili powder, garlic powder, salt, and pepper. Add the thinly sliced beef and toss well to coat. Let it marinate for at least 15 minutes or up to 2 hours in the fridge.
  2. Rice the cauliflower: Remove leaves and core from fresh cauliflower, then pulse in a food processor until rice-like texture or grate with a box grater. Set aside.
  3. Sauté the veggies: Heat 1 teaspoon olive oil in a large skillet over medium-high heat. Add sliced onions and bell peppers. Cook, stirring occasionally, until softened and slightly charred around edges, about 7 to 9 minutes. Season lightly with salt and pepper. Remove and set aside.
  4. Cook the beef: In the same skillet, add oil if needed, then add marinated beef strips in a single layer. Cook without stirring for about 2 minutes, then flip and cook another 2-3 minutes until cooked through but tender. Remove and set aside.
  5. Cook the cauliflower rice: In a separate pan, heat 1 tablespoon olive or avocado oil over medium heat. Add minced garlic if using and sauté for 30 seconds until fragrant. Add riced cauliflower, season with salt and pepper, and cook for 5-7 minutes, stirring occasionally, until tender but not mushy.
  6. Assemble the bowls: Start with a scoop of cauliflower rice, top with sautéed bell peppers and onions, then add beef strips. Finish with optional toppings like fresh cilantro, avocado slices, Greek yogurt, and lime wedges.

Notes

Slice beef thinly against the grain for tenderness. Avoid overcrowding the pan when cooking beef to ensure proper searing. Cook cauliflower rice over medium heat and stir often to prevent sogginess. Rest beef a few minutes after cooking to keep it juicy. Optional toppings add flavor and texture contrast.
