Heat avocado oil in a large skillet over medium-high heat.
Add the diced red onion and red bell pepper, sautéing until the vegetables are slightly softened and fragrant.
Add the ground turkey to the skillet, breaking it up with a spatula, and cook until it is completely browned and no longer pink.
Stir in the chili powder, cumin, garlic powder, sea salt, and black pepper until the turkey is evenly coated in the spice blend.
Add the black beans to the skillet and cook for another 2 minutes until they are heated through.
In a separate small pan or the microwave, lightly steam the cauliflower rice until tender.
Divide the cauliflower rice into bowls, top with the turkey and bean mixture, and finish with fresh avocado slices, cilantro, and a squeeze of lime juice.
