Preheat your grill to medium high heat for a minimum of ten minutes. While the grill is heating, place frozen edamame in grill basket. If you don’t have a grill basket, uncoated metal cooling racks make a great alternative.
Cook edamame in grill basket or atop cooling racks on the grill for approximately 10 minutes, turning once or twice throughout with tongs, until edamame is cooked through and there is some charring throughout the surfaces of the soybeans. Remove from heat and toss in a large bowl with juice of lemon and 2 Tablespoons of flake sea salt. Serve with an additional tablespoon of flake sea salt on top of edamame and eat immediately.
