This lemon and dill vinaigrette is a natural complement to green beans. It's also great tossed with steamed asparagus or drizzled over sliced fresh tomatoes.
Bring an inch of water to a boil in a large saucepan fitted with a steamer basket. Add green beans, cover and cook until tender-crisp, 5 to 7 minutes. Remove from the heat.
Meanwhile, whisk dill, shallot, oil, lemon juice, mustard, salt and pepper in a large bowl. Add the green beans and toss to coat. Let stand about 10 minutes before serving to blend flavors.
To make this recipe serve 10, multiply all the ingredients by 2 1/2: Use 2 1/2 pounds green beans, 3 tablespoons dill, 2 1/2 tablespoons each shallot, oil and lemon juice, 2 1/2 teaspoons mustard and 3/4 teaspoon each salt and pepper.
