In a small saucepan, combine the dry quinoa and water; bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the water is absorbed and the grain is fluffy.
While the quinoa cooks, dice the chicken breast into bite-sized pieces and season thoroughly with chipotle powder, garlic powder, sea salt, and black pepper.
Heat the olive oil in a large skillet over medium-high heat and add the seasoned chicken, cooking for 5-7 minutes until golden brown and cooked through.
Add the sliced red bell pepper and red onion to the skillet, sautéing for 3 to 4 minutes until the vegetables are tender-crisp and slightly charred.
Stir in the rinsed black beans and chopped kale, cooking for another 2 minutes until the kale is vibrant green and slightly wilted.
Remove the skillet from heat and stir in the fresh lime juice to deglaze the pan, ensuring the chicken and vegetables are well coated in the pan juices.
Divide the cooked quinoa into a bowl, top with the spicy chicken and vegetable mixture, and garnish with fresh avocado slices.
