For the cauliflower rice, heat the oil in a medium-large skillet over medium-high heat. Add the riced cauliflower and cook until it starts to soften, about 3 to 5 minutes, stirring frequently so it doesn’t brown. Turn off the heat and stir in the coconut aminos, sesame seeds, salt, and black pepper.
For the chili garlic steak, heat the oil in a medium skillet over medium heat. Add the steak, garlic, red pepper flakes, and salt, and cook until the steak is warm and the garlic is fragrant, about 5 minutes, stirring frequently.
To serve, transfer the cauliflower rice to a serving dish. Pour the chili garlic steak on top. Drizzle on the sesame oil and top with the scallion.
If desired, top each serving with a fried egg.
