Heat a large skillet over medium-high heat and brown the ground beef until fully cooked, breaking it into small crumbles.
Remove the beef from the pan and set aside, leaving a small amount of rendered fat in the pan.
Add the toasted sesame oil to the skillet, then sauté the diced bell peppers until they begin to soften.
Stir in the minced garlic and grated ginger, cooking for 30 seconds until highly fragrant.
Add the cauliflower rice to the pan, stirring frequently for 3 to 5 minutes until tender but still holding a slight crunch.
Push the vegetable mixture to the side of the skillet, crack the egg into the center, and scramble until fully set.
Return the cooked beef to the pan and pour in the coconut aminos, tossing all ingredients together to combine.
Season the dish with sea salt and black pepper, then garnish with sliced green onions before serving immediately.
