Soak your mung beans overnight or for up to eight hours in enough water to cover them by at least three inches. Drain the beans in a colander, give them a thorough wash, and let them sit in the colander, covered with a kitchen towel, until little white shoots appear. It should take 2 days max. If they haven't sprouted yet, rinse them a couple of times a day-- once in the morning and again in the evening -- cover again, and wait.
Once the beans have sprouted cook them in a pressure cooker according to instructions. Alternatlivly cook them in water on the stove. You want the beans to be al dente and not too mushy. Pulse the beans in a food processor or mash them to break them into smaller pieces, but leave some whole for texture.
Preheat the oven to 180 ° C.
