In a sauce pan take the moong dal and turn on the heat in medium. Dry roast to light brown color. Then wash the dal couple of times. In the same pan take 2 cups water and boil the dal until it is soft. You might need more water so check while it is boiling. In a separate pan heat the oil and add cumin and bay leaf. Let them crack, then add the boiled dal (careful it can splatter) and now add all the remaining ingredients. Let them cook for couple of minutes, check the consistency as per your choice.
Enjoy with rice or ruti (Indian flat bread)!
