Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Dice the sweet potato into small half-inch cubes and spread them on the baking sheet, misting lightly with oil and a pinch of salt.
Roast the sweet potatoes for 18-20 minutes until they are tender and slightly golden on the edges.
While the potatoes roast, heat the olive oil in a large non-stick skillet over medium-high heat.
Add the ground chicken to the skillet, breaking it into small crumbles with a wooden spoon until it is fully browned.
Stir in the diced onion, bell pepper, and zucchini, cooking for about 5 minutes until the vegetables reach a crisp-tender texture.
Add the minced garlic, sea salt, black pepper, and dried oregano, sautéing for an additional 2 minutes until fragrant.
Remove the skillet from the heat and serve the savory chicken and vegetable mixture immediately alongside the roasted sweet potato cubes.
