Start by cooking the bulgur. In a pot on medium-high heat add the bulgur, water, tomato paste and vegetable bouillon. Once the water is boiling, reduce to low-heat and cook it until the water evaporates. It should take around 10 minutes.
In the meantime in a bowl add all other ingredients (chopped onions, tomato, parsley, lemon, olive oil, mint). And mix it well.
Wait for the bulgur to cool-down before adding it to the bowl. You can also make the bulgur on the day before to save time. Add the bulgur to the bowl and adjust salt and black pepper as per your taste.
Serve it as a very refreshing side dish. It sides great with falafel, shakshuka, grilled chicken, hummus, pita bread, inside chicken wraps.
