Preheat your oven to 400°F.
Wash and cut the sweet potato into 1/2-inch cubes. Toss with a portion of olive oil, salt, and pepper, and spread out on a baking sheet.
Roast the sweet potato cubes in the preheated oven for about 20-25 minutes until tender and slightly caramelized.
While the sweet potatoes roast, heat a skillet over medium heat. Add the remaining olive oil.
Dice the onion and mince the garlic. Sauté them in the skillet until the onion becomes translucent and soft.
Add the ground chicken to the skillet, breaking it up with a spatula. Cook until the chicken is no longer pink.
Stir in the mixed fresh herbs, and season with salt and pepper to taste.
Once the chicken is cooked through and well-seasoned, fold in the fresh spinach and allow it to wilt, which takes about 1-2 minutes.
Plate the herb-seasoned ground chicken mixture and top with the roasted sweet potatoes.
Serve warm for a balanced, nutrient-rich meal.
