Briefly wash the bulgur in a colander under cold water. Then bring to the boil in the vegetable or chicken stock and simmer at a low temperature for 15 - 30 minutes (depending on your taste).
While the bulgur is cooking, the vegetables can be cut: finely chop the onion and add to the bulgur. Squeeze the garlic clove and let it simmer as well.
Dice tomatoes, cucumber, bell pepper and feta cheese and place in a bowl. Squeeze half a lime over it.
Mix the cooked bulgur with the tomato paste and pumpkin seed oil (walnut oil certainly tastes very good too) and mix with the vegetables. Finally fold in the walnuts and parsley and serve.
