"A delicious, hot Asian appetizer, great for dinner parties on a budget or a way above-average party dish. Pour edamame onto a platter and serve - it's nice to give each person a small dish to discard the soy bean shells."
Heat peanut oil in a skillet over medium-low heat; add garlic. Cook and stir garlic until slightly browned, 2 to 3 minutes. Add edamame; cook and stir until glossy and puffed, 1 to 2 minutes. Stir black bean sauce into edamame until evenly coated and warmed, 1 to 2 minutes.
