In a food processor or blender, pulse cauliflower florets to resemble rice. Do this in batches and set aside.
In a large nonstick skillet, heat olive oil and cook garlic, ginger and onions until soft and fragrant.
Add cauliflower, broccoli and carrots, stir and continue to cook until soft. Add water 2 tablespoons at a time if needed (this will help to steam the vegetables).
Add peas, then stir to combine. Make a well in the center of the vegetable mixture and scramble in the egg.
Add sesame oil and soy sauce. Stir to combine and season to taste.
Top with sesame seeds and sliced pickled radish.
Serve immediately.
