Dice the sweet potato into small, uniform cubes and finely chop the chicken breast, bell peppers, and red onion.
Heat the olive oil in a large skillet over medium-high heat until shimmering.
Add the sweet potatoes to the skillet and cook for 8-10 minutes, stirring occasionally, until they are tender and slightly browned.
Push the potatoes to the side of the pan and add the diced chicken, bell peppers, and onions to the center.
Season the entire mixture with smoked paprika, garlic powder, sea salt, and black pepper.
Sauté for another 6-8 minutes, tossing frequently, until the chicken is fully cooked through and the vegetables are soft.
Garnish with fresh parsley and serve immediately for a balanced, high-protein pre-workout meal.
