1 1/4 lb red potatoes, quartered

3 Tbsp minced shallots

3 Tbsp white wine vinegar

4 Tbsp olive oil, divided

1 Tbsp Dijon mustard

1 tsp sugar

1/2 tsp each kosher salt and black pepper

3 cups arugula

BOIL potatoes in a saucepan of water over high heat until tender - 8 minutes. Drain, rinse, and spread on a baking sheet; chill until cold.

WHISK together shallots, vinegar, oil, Dijon, sugar, salt, and pepper in a large bowl until combined.

SAUTE chilled potatoes in a cast-iron skillet over medium heat in 1 layer until browned on 1 side, about 10 minutes. Stir potatoes and continue to brown until crisp, 10-15 minutes more. Toss warm potatoes with vinaigrette and arugula until coated.
