Ingredients

Instructions

  1. Step 1: Using a food processor or box grater, pulse or grate 1 medium cauliflower head into rice-sized pieces (about 4 cups). Set aside.
  2. Step 2: Heat 2 tbsp avocado oil in a large skillet or wok over medium-high heat until shimmering. Add 3 minced garlic cloves and 1 tbsp grated fresh ginger, sautéing for 30 seconds until fragrant.
  3. Step 3: Add 1 diced red bell pepper and 1 diced yellow bell pepper to the skillet. Stir-fry for 4-5 minutes until peppers begin to soften but remain crisp.
  4. Step 4: Add the riced cauliflower and 3 sliced green onions to the skillet along with 2 tbsp coconut aminos, 1 tsp sea salt, and 1/2 tsp black pepper. Stir-fry for 5-6 minutes until the cauliflower rice is tender but not mushy.
  5. Step 5: Remove the skillet from heat and drizzle 1 tbsp toasted sesame oil over the stir-fry, tossing to combine. Garnish with 1/4 cup chopped fresh cilantro before serving warm.
