In a large non-stick skillet or wok over medium-high heat, add the toasted sesame oil.
Add the shrimp and cook for 2-3 minutes until pink and opaque, then remove from the pan and set aside.
Whisk the eggs in a small bowl and pour into the pan, scrambling until just set, then remove to join the shrimp.
Add the minced garlic, grated ginger, diced carrots, and peas to the pan, sautéing for 3 minutes until the carrots are slightly tender.
Stir in the cauliflower rice and cooked brown rice, cooking for 4-5 minutes until the cauliflower rice is tender and moisture has evaporated.
Return the shrimp and eggs to the pan, drizzle with tamari, and season with sea salt and black pepper.
Toss everything together until well combined and heated through, then garnish with sliced green onions.
