Preheat your oven to 400°F.
Peel and cube the sweet potato into bite-sized pieces.
Toss the sweet potato cubes with one teaspoon of olive oil, salt, and pepper on a baking sheet.
Roast the sweet potatoes for 20-25 minutes until they are tender and slightly browned.
Season the chicken thighs with salt, pepper, and dried herbs like oregano or thyme.
Heat a large skillet over medium-high heat with the remaining teaspoon of olive oil.
Sear the chicken thighs for about 6-7 minutes per side until they reach an internal temperature of 165°F.
Remove the chicken from the pan and let it rest.
In the same skillet, add the trimmed green beans and minced garlic with a splash of water.
Sauté for 4-5 minutes until the green beans are tender-crisp and the garlic is fragrant.
Serve the seared chicken alongside the roasted sweet potatoes and garlic green beans.
