  • 2 tbsp (30ml) Avocado Oil Divided use
  • 1 large Red Bell Pepper Sliced into strips
  • 1 large Yellow Bell Pepper Sliced into strips
  • 1 large Red Onion Cut into wedges
  • 2 cups (475ml) Cauliflower Rice Fresh or frozen
  • 1/4 cup (60ml) Sour Cream Thick and smooth
  • 1/4 cup Fresh Cilantro Whole leaves
  • 1 whole Lime Cut into wedges

Equipment

  • 1 Cast-Iron Skillet Essential for getting a deep sear and visible grill marks.
  • 1 Meat Thermometer To ensure perfect medium-rare steak (130-135°F).

Method
 

Steak Preparation
  1. Heat 1 tbsp oil in a skillet over high heat. Sear steak strips until visible grill marks appear and internal temp reaches 130°F (54°C). Rest for 5 mins.
Vegetable Sauté
  1. In the same pan, add remaining oil and sauté peppers and onions until blistered and charred on the edges but still crisp.
Assembly
  1. Layer cauliflower rice in a matte black bowl. Top with steak sections, charred peppers, and onions. Add sour cream, cilantro, and a lime wedge.

Notes

For the best flavor, season the steak with cumin and smoked paprika before searing.
Always slice the steak against the grain for maximum tenderness.
