Place a medium/large pot or casserole on medium heat and pour the oil. Wait for 2’ to heat-up and then add the peppers and onions, sautéing them for about 6’ to soften.
Add the tomato paste and stir well. Add the peppercorns (or paprika) along with the coriander, sugar, thyme and sultanas and mix well.
Time for the bulgur along with the water and salt, mix well and bring to a boil. Turn off the heat and leave for about 22’ with the lid on.
If you want a dryer Bulgur, you can optionally proceed with placing a towel in-between the pot and the lid and set aside for 5-10’ more to absorb the excess humidity.
