Preheat your oven to 400 degrees. Boil water in a medium pot. Depending on your preference, you can salt the water, about 1/2 tablespoon for salt lovers or 1 teaspoon for less salt. Add edamame a small handful at a time, being careful not to splash boiling water. Boil for 5-6 minutes, testing the beans occasionally. Edamame should be firm with a little give. Mushy beans are overcooked beans! When cooked, drain the edamame and salt to taste. Spread the edamame out on a baking sheet and drizzle with olive oil. Sprinkle grated cheese over the beans and season with salt and pepper to taste. Bake in the oven until the cheese is golden, about 15 minutes. Squeeze the beans out of the shells in your mouth to eat, discarding the shells!
