Heat the avocado oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it up with a spatula until browned and thoroughly cooked.
Stir in the chili powder, cumin, garlic powder, sea salt, and black pepper to season the meat.
Add the diced red onion and red bell pepper to the beef mixture, sautéing for 3-4 minutes until the vegetables are tender.
In a separate pan or microwave-safe bowl, lightly steam the cauliflower rice until it reaches a tender consistency.
Stir the rinsed black beans into the beef and vegetable mixture until they are heated through.
Assemble the bowl by placing the cauliflower rice at the base and topping it with the savory beef and bean mixture.
Finish the bowl with a dollop of Greek yogurt, fresh salsa, and a sprinkle of chopped cilantro.
