Wash and dry all produce. Preheat oven to 400 degrees. Cut potatoes into 1/2-inch cubes. On a baking sheet, toss potatoes, carrots, Herbs de Provence, a drizzle of olive oil, and a pinch of salt and pepper. Roast in oven until lightly browned, 25-30 minutes, tossing halfway through.

Peel, halve, and thinly slice onion. Mince or grate garlic. Halve grape tomatoes lengthwise.

Heat a drizzle of olive oil in a large pan over medium-high heat. Season chicken breasts all over with salt and pepper. Sear in pan until browned and almost cooked through, 3-4 minutes per side. Remove from pan and set aside on a second baking sheet (or in a baking dish)

Add onion and a drizzle of olive oil to same pan over medium-low heat. Cook until softened, about 5 minutes. Toss in garlic, tomatoes, balsamic vinegar, and honey. Cook until vinegar and any juices are slightly thick, about 2 minutes. Stir in 1 TBSP butter.

Spoon glaze (including onions and tomatoes) over chicken. (TIP: It’s OK if some glaze runs onto baking sheet.) Bake in oven until chicken is cooked through, 5-7 minutes

Divide roasted veggies between plates, then add a chicken breast to each. Spoon any loose onions, tomatoes, and glaze on top.
