Saucy Barbecue Chicken

Place potatoes in a large pot of salted water. Bring to a boil and cook until easily pierced by a knife, 10-12 minutes. Using a slotted spoon, transfer potatoes to a large bowl, keeping pot of boiling water on stove. Place bowl in refrigerator to cool potatoes.

Heat a large drizzle of oil in a large pan over medium-high heat. Season chicken all over with salt and pepper. Add to pan and cook until browned and nearly cooked through, about 5 minutes per side. Add barbecue sauce and reduce heat to low. Cook, tossing to coat chicken, until sauce is thick and glazelike, 1-2 minutes more.

Add green beans to pot with boiling water. Cook until tender but still crisp, 3-4 minutes. Drain, then rinse under cold water. Shake green beans in strainer over sink to dry.

Add green beans, scallion whites, mayonnaise, and 4 tsp white wine vinegar (we sent more) to bowl with potatoes. Toss to combine. Season with salt and pepper.
