Grate the cauliflower. If using fresh cauliflower, grate it on the large holes of a box grater or pulse it in a food processor fitted with a medium or large shredding disk. Set aside.

Cook the eggs. Beat the eggs in a small bowl with a pinch of salt. Heat 1 tablespoon of peanut oil in a large skillet over medium heat. Add the eggs and cook, stirring and breaking them into small pieces, until just set. Transfer to a plate and set aside. Wipe out the skillet.

Sauté the aromatics. Add 2 tablespoons of peanut oil to the skillet and return it to medium heat. Add the onions and cook, stirring, until softened and translucent, about 3 to 4 minutes. Stir in the garlic and ginger and cook for 1 to 2 minutes more, stirring constantly to avoid burning.

Add the cauliflower rice. Stir in the grated cauliflower, soy sauce, and chili paste. Cook for 4 to 5 minutes, stirring frequently. Add the mixed vegetables and continue cooking for another 5 minutes, until tender.

Finish and serve. Stir in the sesame oil and scallions, then return the cooked eggs to the skillet. Toss everything together and taste, adding more salt or soy sauce if needed. Heat through and serve warm.
