There's no better compliment to a barbecue dish than a side of grilled green beans. This Grilled Green Beans recipe is great for summer night barbecues.
Preheat an outdoor grill, stove-top grill pan, or griddle to medium-high. Place the green beans in a large bowl, add 2 teaspoons of the oil and toss to coat the green beans with the oil. Place the green beans in a vegetable basket and place the basket on the grill or arrange the green beans on the foil or grill pan. Grill 3–5 minutes, turning frequently, until the green beans are golden brown and crisp-tender.
Meanwhile, in a small bowl, whisk together the remaining tablespoon of oil, 2 tablespoons of the lemon juice, ½ teaspoon of finely grated lemon zest, shallots, mustard powder, and thyme.
Transfer the green beans to a large bowl, add the lemon vinaigrette, and toss to coat. Season to taste with salt and pepper.
