Heat the butter and toasted sesame oil in a large skillet over medium heat. Add the edamame and cook, stirring often, for 3-4 minutes.
Add the soy sauce and garlic and cook, stirring constantly for 1-2 minutes.
Remove from the skillet and serve. Enjoy!
Side Note: To eat whole edamame, simply put the pod into your mouth, bite down and pull through your teeth (similar to eating an artichoke leaf), the soybeans pop out of the pod and into your mouth. Discard the pods.
