Trim green beans and cut slant-wise into 2-3" pieces. Or keep long if desired.
Steam the green beans by using a steamer basket or placing them in a large skillet with ½ cup of water. Bring the water to a boil and cook covered until the beans are tender, about 6-8 minutes. You can boil them too.
Meanwhile melt butter in a small saucepan over low heat. Add the almonds and cook until the almonds are slightly browned, about 5-7 minutes.
When the beans are done, drain them and return them to the pan, pour over the butter and almonds and toss.
