Heat the avocado oil in a large skillet over medium-high heat.
Add the ground turkey to the skillet, breaking it apart with a spatula, and season with sea salt, black pepper, chili powder, cumin, garlic powder, and cayenne pepper.
Cook the turkey until it is browned and mostly cooked through, about 5-7 minutes.
Stir in the diced red bell pepper and red onion, sautéing for another 4 minutes until the vegetables are tender-crisp.
Add the black beans and corn kernels to the skillet, tossing everything together for 2 minutes to heat through.
Place the warm cooked brown rice into a serving bowl.
Spoon the turkey and vegetable mixture over the rice.
Top the bowl with sliced avocado, fresh cilantro, a drizzle of lime juice, and salsa verde before serving.
