Peel and cube the sweet potato into half-inch pieces and dice the chicken breast into bite-sized chunks.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the sweet potato cubes to the skillet and cook for 8 minutes, stirring occasionally, until they are tender and caramelized.
Push the potatoes to one side of the pan and add the chicken, seasoning the entire pan with sea salt, black pepper, and garlic powder.
Sauté the chicken for 5-6 minutes until cooked through and golden brown.
Stir in the diced bell peppers and tomatoes, cooking for another 2 minutes until the peppers soften slightly.
Add the chopped Pak Choi to the skillet and toss for 1 minute until the leaves are just wilted but the stems remain crisp.
Transfer the mixture to a bowl and garnish with chia seeds before serving.
