This is a quick and healthy side dish to any Sunday dinner.
Preheat oven to 350 degrees. Bring a large pot of salted water to a boil. Add green beans; cook until bright green and tender, 6 to 8 minutes. Drain in a colander; rinse under cold water, and pat dry.
Meanwhile, spread nuts in a single layer on a baking sheet; toast in oven until golden brown and fragrant, about 7 minutes. Transfer to a plate to cool.
In a large bowl, toss green beans with oil; season with salt and pepper. Transfer to a serving dish. Garnish with toasted almonds.
