Cook the brown rice according to package instructions and set aside.
Press the tofu between paper towels to remove excess moisture, then cut into 1-inch cubes.
In a large skillet or wok, heat the avocado oil over medium-high heat.
Add the tofu cubes to the skillet and sear until golden brown on all sides, then remove and set aside.
Add the shrimp, minced garlic, and grated ginger to the same skillet, sautéing until the shrimp is pink and opaque.
Toss in the broccoli and sliced bell pepper, cooking for 3-4 minutes until the vegetables are tender-crisp.
Return the tofu to the pan and drizzle with tamari and toasted sesame oil.
Season with sea salt and black pepper, tossing everything together for 1 minute to combine the flavors.
Serve the stir-fry immediately over the warm brown rice.
