Rice the cauliflower: Cut the cauliflower into florets.
Pulse in a food processor until it looks like rice. Work in batches and stop before it turns mushy. Pat dry with a clean towel if it seems wet.
Prep the aromatics and veggies: Dice the onion, mince the garlic and ginger, and chop the carrots and peppers.
Keep peas and green onions nearby.
Scramble the eggs (optional): Heat 1 teaspoon oil in a large skillet or wok over medium heat. Add eggs and scramble just until set. Transfer to a plate.
Sauté aromatics: Add 1 tablespoon oil to the pan.
Cook onion for 2–3 minutes until softened. Stir in garlic and ginger for 30 seconds until fragrant.
Add veggies: Stir in carrots and bell pepper. Cook 3–4 minutes until they start to soften but still have bite.
Cook the cauliflower rice: Push veggies to the sides.
Add remaining oil and then the cauliflower rice. Spread it out. Let it cook undisturbed for 2 minutes to get a bit of color, then stir.
Cook 4–6 minutes total until tender-crisp.
Season and combine: Add soy sauce, sesame oil, peas, and any cooked protein. Return the scrambled eggs. Toss to coat evenly.
Taste and add more soy sauce, pepper, or heat as needed.
Finish: Turn off heat. Stir in green onions and a pinch of red pepper flakes or a drizzle of sriracha if you like spice. Serve hot.
