Green Beans & Pancetta with Whole-Grain Mustard Dressing

Heat a large skillet over medium heat. Add pancetta and cook, stirring often, until crispy, about 5 minutes. Transfer with a slotted spoon to a paper-towel-lined plate.

Add shallot and green beans to the pan. Cook, stirring, until fragrant, 1 to 2 minutes. Add water and salt. Cover and cook until the beans are tender and the water has evaporated, about 8 minutes. Remove from heat and toss with mustard, pepper and the reserved pancetta. Transfer to a serving dish.
