Place the fine bulgur in a large mixing bowl and pour hot water over it. Cover and let it sit for 10–15 minutes until the bulgur softens and absorbs the water completely.
In a separate bowl, whisk together olive oil, tomato paste, pepper paste, pomegranate molasses, lemon juice, salt, black pepper, and red pepper flakes until smooth and fully combined.
Fluff the softened bulgur with a fork to separate the grains, then pour the prepared dressing over it. Mix thoroughly and gently knead for 2–3 minutes to help the bulgur absorb the flavors.
Add the chopped green onions, parsley, tomato, and optional cucumber. Fold everything together until evenly distributed.
Let the kısır rest for about 10 minutes before serving to allow the flavors to meld. Taste and adjust seasoning if needed, then serve fresh.
