If using frozen Koldūnai, thaw them in the refrigerator overnight or by submerging them in cold water for about 30 minutes. Gently pat them dry.

Heat a large non-stick frying pan over medium heat. Add the butter and olive oil. Swirl to coat the bottom of the pan.

Carefully place the Koldūnai in a single layer in the hot pan, ensuring not to overcrowd it. Cook for 4-5 minutes until golden brown and crispy on the bottom.

Gently flip each Koldūnai and cook for another 3-4 minutes on the other side until golden and heated through. They should feel soft when gently pressed.

If using, sprinkle with a pinch of salt and black pepper while still in the pan.

Remove the Koldūnai from the pan and arrange them on a serving plate.

Garnish with fresh parsley if desired. Serve immediately and enjoy your crispy, tender Koldūnai breakfast!
