Dice the chicken breast and sweet potato into small, uniform half-inch cubes to ensure they cook quickly and evenly.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the sweet potato cubes to the pan and sauté for 8 to 10 minutes, stirring occasionally, until they are softened and lightly browned.
Push the potatoes to one side of the skillet and add the chicken cubes, garlic powder, smoked paprika, sea salt, and black pepper.
Cook the chicken for 5 to 6 minutes, stirring frequently, until the pieces are golden and no longer pink inside.
Add the broccoli florets and the tablespoon of water to the skillet, then immediately cover with a lid.
Steam for 2 to 3 minutes until the broccoli is vibrant green and tender, then remove the lid and toss everything together before serving.
