Remove the core and let the cauliflower dry completely. Coarsely chop into florets, then place half of the cauliflower in a food processor and pulse until the cauliflower is small and has the texture of rice or couscous (don't over process or it will get mushy). Set aside and repeat with the remaining cauliflower.
Combine egg and egg whites in a small bowl and beat with a fork. Season with salt.
Heat a large saute pan or wok over medium heat and spray with oil. Add the eggs and cook, turning a few times until set. Set aside.
Mince garlic and dice onion fine. Dice scallion, green and whites, separated.
Add the sesame oil and saute onions, scallion whites, peas and carrots and garlic about 3-4 minutes, or until soft.
Raise the heat to medium-high. Add the cauliflower "rice" to the saute pan along with soy sauce. Mix, cover and cook approximately 5-6 minutes, stirring frequently, until the cauliflower is slightly crispy on the outside but tender on the inside.
Add the egg. Remove from heat and mix in scallion greens.
