Sauté onion in the oil on medium heat until translucent. Add peppers and cook for another minute. Add the tomato and cook until the tomato is completely cooked and softened. Add the bulgur and stir, allowing it to soak up the liquid from the tomato. Add 2 cups hot water and at
least 1⁄2 teaspoon salt.
Lower the heat, cover, and allow to cook until all water is absorbed, about 10 to 15 minutes.
Once water is absorbed, remove pot from heat, wrap a dish towel or paper towel over the lid, then cover pot with the lid, allowing excess moisture to be absorbed, approximately 5 minutes.
Fluff with a fork before serving. Top with chopped parsley (optional).
