Preheat your oven to 425°F.
Prepare the sweet potato by washing it thoroughly. Cube the sweet potato into evenly sized pieces, toss with a teaspoon of olive oil, and season lightly with salt and pepper. Spread on a baking sheet.
Trim the ends of the green beans and toss them lightly with a bit of salt, pepper, and a pinch of mixed herbs. Place them on a separate section of the baking sheet or on another tray.
Roast the sweet potato and green beans in the preheated oven for 20-25 minutes, stirring halfway through, until tender and lightly crispy.
Season the chicken breast with salt, pepper, minced garlic, and the remaining mixed fresh herbs. In a non-stick skillet over medium-high heat, sear the chicken for about 3-4 minutes on each side until golden, then reduce heat and cook until the internal temperature reaches 165°F (about 5-7 minutes).
While the chicken rests, prepare the creamy herb sauce by stirring the nonfat Greek yogurt with a pinch of salt, pepper, and any extra chopped herbs if desired.
Slice the cooked chicken breast, then plate alongside the roasted sweet potato and crispy green beans. Drizzle or serve the creamy herb sauce on the side.
