Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into 1-inch cubes, then toss them with half of the olive oil and a pinch of sea salt.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes until they are tender and golden brown.
While the potatoes roast, mince the garlic cloves and finely grate the fresh ginger.
Heat the remaining olive oil in a large skillet over medium-high heat, then add the chicken breast strips and sear until browned.
Add the sliced mushrooms, green peppers, carrots, and celery to the skillet, sautéing for 5-7 minutes until the vegetables are tender-crisp.
Stir in the minced garlic, grated ginger, and ground coriander, cooking for an additional 2 minutes until the aromatics are fragrant.
Season the chicken and vegetable mixture with the remaining sea salt and black pepper.
Plate the roasted sweet potatoes and top with the ginger-garlic chicken and vegetable medley for a complete, clean meal.
