Mushroom and Grain Cheeseburgers - Recipes for Health Mushroom and Grain Cheeseburgers Barley is a traditional hearty partner for mushrooms, but brown rice is just as tasty in this burger. 1/2 cup finely chopped onion 1 1/4 pounds mushrooms, sliced 2 teaspoons chopped fresh sage 1 1/4 cups cooked brown rice or barley 1/4 cup chopped fresh parsley 3/4 cup cooked chickpeas (1/2 can) 2 ounces Gruyère cheese, sliced very thin with a cheese slicer Heat 1 tablespoon of the oil over medium heat in a heavy ovenproof skillet and add the onion. Cook, stirring, until it is tender, about 3 minutes. Turn the heat up to medium-high and add the mushrooms. Cook, stirring often, until the mushrooms have begun to sweat and soften, about 3 minutes. Turn the heat back down to medium, add a generous pinch of salt, the garlic and sage, and continue to cook until the mushrooms are tender, about 3 minutes. Taste, adjust seasoning and remove from the heat. Place half the mushrooms in a food processor fitted with the steel blade and the other half in a large bowl, along with the rice or barley and the parsley. Add the chickpeas and egg to the food processor and purée with the mushrooms. Stir into the rice and mushroom mixture and mix everything together. Add the remaining tablespoon of oil to the pan and, working in batches if necessary, cook the burgers for 2 minutes on one side, until nicely browned. Bake 5 minutes. Remove the pan from the oven and lay thin slices of Gruyère on top of each burger. Return to the oven and bake for another 5 minutes, or the patties are lightly browned and the cheese has melted.
