Rinse the lentils and place them in a pot with water. Boil until tender.

Rinse the rice and add it to the lentils with salt and more water. Once it comes to a boil, reduce the heat and simmer until the water is absorbed and the rice is cooked.

In a skillet, heat the olive oil and vegetable oil. Slice the onion into thin strips and fry until golden brown. Remove the onions and set aside. Pour the oil used for frying the onions over the rice and stir. Transfer the rice to a serving dish and top with the fried onions.
