Pomidor dolma (tomatoes with meat)

As I have posted earlier I make Dolmas with different vegetables. Today I make with tomatoes:) Dolma is very healthy meal, because it is prepared by stewing. All vegetables will remain their vitamins. It is easy and very yummy treat for dinner.
Ingredients:
Filling:
300 gr of minced meat(usually lamb)
100 gr rice
1 finely chopped onion
3 tbsp butter
1 egg
Salt as taste
1 tsp of pepper, ground coriander, cumin seeds
For shape:
Tomatoes, it depends on your tomatoes size. Take as much tomato as all your filling will be used up
For base:
60 gr vegetable oil
1 onion chopped
All remaining tomato content that was take out
Sour cream for serving
Wash your tomatoes carefully, cut the top and take out all of content with small teaspoon. Fill with meat. Fill all of your tomatoes in this way. Heat up oil, put onion and fry until golden add tomato content continue frying until smooth. Reduce heat. Put carefully all of tomatoes in pot face up. Pour some water that covers tomatoes for 2/3. Bring to boil, then cover the lid of your pot. Cook until rice is ready for approximately 30-40 min. Take from heat, take tomatoes very carefully as they are soft and barely hold their shape.
Serve with some vegetables and sour cream:)
