Roast Chicken with Lemon and Green Beans

I adapted this recipe I found on Pinterest from Real Simple Magazine. The original recipe included potatoes, but since I'm not eating those, I edited them out.

 Ingredients

6 tablespoons olive oil
2 lemons, 1 thinly sliced, 1 juiced
4 cloves garlic, minced
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
3/4 pound trimmed green beans
4 chicken breasts (bones left in, with skin, about 3 1/4 pounds)

Directions

1. Preheat oven to 450°F. Coat a large baking dish or cast-iron skillet with 1 tablespoon of the olive oil. Arrange the lemon slices in a single layer in the bottom of the dish or skillet.
2. In a large bowl, combine the remaining oil, lemon juice, garlic, salt, and pepper; add the green beans and toss to coat. Using a slotted spoon or tongs, remove the green beans and arrange them on top of the lemon slices.  Place the chicken in the same bowl with the olive-oil mixture and coat thoroughly. Place the chicken, skin-side up, in the dish or skillet. Pour any of the remaining olive-oil mixture over the chicken.
3. Roast for 50 minutes. Remove the chicken from the dish or skillet. Place the beans and potatoes back in oven for 10 minutes more or until the potatoes are tender. Place a chicken breast on each of 4 serving plates; divide the green beans and potatoes equally. Serve warm.
