Preheat your oven to 400°F.
Slice the sweet potato into 1/2-inch rounds or cubes. Toss with a pinch of salt, pepper, and half the olive oil. Roast on a baking sheet for 20-25 minutes until tender and slightly caramelized.
Season the chicken breast with salt, pepper, and minced garlic. Sauté the chicken in a skillet over medium heat until both sides are golden and the chicken is cooked through, about 6-7 minutes per side.
While the chicken cooks, steam or blanch the green beans for 3-4 minutes until crisp-tender.
In a small bowl, mix the Greek yogurt with a pinch of salt, pepper, and a dash of minced garlic to create a light cream sauce.
For extra crispiness, toss the green beans in the remaining olive oil and briefly pan-fry them in a hot skillet for about 2 minutes.
Plate the chicken, arrange the roasted sweet potatoes and crispy green beans on the side, and drizzle the creamy yogurt sauce over the chicken.
Enjoy your balanced, flavorful meal!
