When the vegetables turn golden brown, add 2-3 tablespoons of water and the rice.

Choose the softer, easier to handle cabbage leaves for the sarmale. Rinse with water if they seem too salty.
Place a small amount of the filling on the cabbage leaf and roll to your preferred size. Place in a clay pot or non-stick pan (place some chopped pickled cabbage on the bottom of the pot to make sure the rolls don't stick).
Once the pan is filled with cabbage rolls, cover them with the water and the rest of the tomato paste (optionally add extra thyme) mixed together, and simmer for about an hour (or until the cabbage is soft and easy to cut. The cooking time will depend on the thickness of the leaf and how pickled it is.
Serve with sour cream or Greek yogurt, while for the vegan version you can try soy cream or coconut yogurt. Don't forget the chili, polenta or freshly baked bread.
