In a large saucepan on medium heat place the onion, celery carrots, and bay leaves. Stir frequently, adding water so the veggies don’t stick to the pan, for about 5 minutes.
Add the tomatoes, dal, rice, all spices, and water. This is a good time to add optional veggies as well.
Bring to a boil and then let simmer, lightly covered until the dal and rice are cooked (about 20 minutes). Add olive oil and salt to taste.
