I used a 300g bag of frozen edamame to yield 3/4 cup shelled edamame. Cook edamame as per package directions. Submerge in cold water to stop the cooking process. Drain and shell.
Should you prefer a smoother texture, process all the edamame and chickpeas together in the first blend.
Yields approximately 2 cups of filling which will make 4-6 sandwiches.
