When it starts to boil, reduce the heat and boil the lentils for 5 more minutes. Turn off the heat and let the lentils stand for the next step without straining.
In a separate pan, mix the butter and vegetable oil, add the finely chopped onion and sauté until it turns a little pink.
Add the bulgur and salt and mix.
Add the boiled lentils with their water and mix.
Flatten your lentil bulgur mixture in the pan.
Add hot water (just one finger over the bulgur), turn the stove to the lowest heat, and cover the pot.
Cook your pilaf over low heat until the water is absorbed. (about 15-20 minutes)
Turn off the heat after your meal is cooked, stir the pilaf only once, close the lid of the pan and let the rice rest for half an hour.
