In a high-speed blender or food processor add the basil leaves and the water and blend well. Pour the basil infused water through a fine mesh strainer and keep about 800 ml. Don’t worry if it looks dark green!
In a small/medium pot add the oil on medium heat for 1 minute. Add the onion and sauté until translucent.
Add the bulgur and keep on sautéing for a minute or until the bulgur is well tossed with the oil.
Add the basil infused water, season with the salt and pepper, and bring to a boil. Keep stirring for a minute and then take of the heat and cover with the lid for 10 minutes for the bulgur to absorb all the liquid.
Finally uncover and place a kitchen towel to absorb any remaining humidity, for further 10 minutes.
