In a small bowl, whisk together the coconut aminos, grated fresh ginger, and red pepper flakes to create the bulgogi sauce base.
Bring a small pot of water to a boil, gently lower the egg in, and cook for 6.5 minutes; immediately transfer to an ice bath to ensure a silky yolk.
Heat a large skillet over medium-high heat with half of the sesame oil and brown the ground beef until fully cooked, breaking it into small crumbles.
Add the minced garlic to the beef and cook for 1 minute until fragrant, then pour in the coconut aminos mixture and simmer for 2 minutes until the sauce coats the meat.
In a separate pan, sauté the cauliflower rice, shredded carrots, and baby spinach with the remaining sesame oil until the spinach is wilted and the cauliflower is tender.
Assemble the bowl by layering the savory beef over the vegetable base, then top with the peeled and halved egg, sliced green onions, and sesame seeds.
