Chop top (not tail) off of green beans and cut into 1-2 inch pieces.
In a large pot with a steamer, add about 2 inches of water, cover, and set on high until the water boils. Lower heat, add green beans, and steam covered for 3 minutes or until beans are cooked, but still crunchy. Set aside.
Meanwhile, in a small bowl combine mustard, extra virgin olive oil, white wine vinegar, and maple syrup. Mix well.
In a large serving bowl, combine steamed green beans, almonds, and dressing. Toss and serve immediately.
