Prepare the Cauliflower. Rinse and dry your cauliflower, then pulse in a food processor until it resembles rice. If using pre-riced cauliflower, drain excess water to avoid soggy fried rice.
Cook the Vegetables. Heat a bit of oil in a large skillet or wok. Add onions, carrots, and bell peppers, sautéing until just tender. Stir in garlic and ginger for about 30 seconds until fragrant.
Scramble the Eggs. Push the vegetables to one side of the pan, add lightly beaten eggs to the empty side, and scramble until cooked. Mix eggs with the vegetables.
Add Cauliflower and Sauce. Toss in the riced cauliflower, soy sauce, and sesame oil. Stir-fry for 5–7 minutes until the cauliflower is tender but not mushy.
Finish and Serve. Top with sliced green onions and additional sesame oil if desired. Serve immediately as a main dish or side.
