In a large pot, heat the olive oil and add the onions. Cook for 3 minutes. Add the garlic and cook for another minute. Add the mung beans, spices, salt and pepper, stir well to combine. Add water, cover and cook until the beans are tender, approximately 35 to 40 minutes. Check the beans after 20 minutes to make sure they have enough water.
