Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).
Toss asparagus with a light mist of cooking spray and salt, then roast on a baking sheet for 12 to 15 minutes until tender-crisp.
In a large non-stick skillet over medium-high heat, cook the ground turkey with garlic powder, cumin, chili powder, and salt until browned and fully cooked (165 degrees Fahrenheit internal temperature).
In a separate skillet over medium heat, sauté cauliflower rice for 5-7 minutes until softened; stir in lime juice and cilantro.
Divide the cilantro-lime cauliflower rice into four meal prep containers or bowls.
Top the rice with equal portions of the cooked turkey, roasted asparagus, and black beans.
Garnish each bowl with sliced radishes, a dollop of Greek yogurt as a high-protein sour cream substitute, and avocado slices.
