Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1.5 lbs halved baby potatoes with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper on a large baking sheet. Roast for 15 minutes.
  2. Step 2: Season 4 chicken breasts (6 oz each) with 1/2 tsp salt, 1/4 tsp black pepper, and 1/2 tsp dried thyme. Heat 1 tbsp olive oil in a large skillet over medium-high heat.
