In a small bowl, whisk together the soy sauce, chicken broth, brown sugar, sesame oil, ginger, and chili flakes until smooth. Set the sauce aside.
In another small bowl, combine the cornstarch and water to make a smooth slurry. Set aside.
Heat the cooking oil in a large skillet over medium-high heat.
Add the minced garlic and cook for about one minute, stirring constantly until fragrant.
Add the ground turkey to the skillet. Break it apart with a wooden spoon while cooking until browned and fully cooked, about 5 to 6 minutes.
Stir in the zucchini strips and most of the chopped green onions, reserving a small amount for garnish.
Pour the prepared sauce over the turkey mixture and stir until everything is evenly coated. Cook for 3 to 4 minutes, allowing the zucchini to soften.
Stir in the cornstarch slurry and continue cooking for another minute until the sauce thickens and coats the turkey beautifully.
Taste and season with salt and freshly ground black pepper if needed.
To assemble the Asian Turkey and Avocado Brown Rice Bowls, divide the cooked brown rice evenly among four serving bowls.
Spoon a generous portion of the turkey and zucchini mixture over the rice.
Arrange the sliced avocado alongside the turkey. Sprinkle a small pinch of sea salt over the avocado if desired to enhance its flavor.
Top each bowl with a poached egg.
Finish with sesame seeds and the reserved green onions before serving.
