Fill a large pot with about 1 inch of water and bring to a boil. When boiling, add beans and steam/boil until tender but not mushy, about 5 minutes. Drain beans.
In the meantime, toast your almonds in a 350 degree oven for about 10 minutes or until fragrant. Cool the almonds then chop into quite small pieces.
Heat a large skillet. Add the olive oil and beans and toss until warm and coated with oil. Remove beans to a large bowl and add balsamic, almonds and salt and pepper to taste. Serve warm.
