Kotlety with Wild Mushroom Sauce

MEAT PATTIES:--
500 g ground beef
500 g ground pork
1 onion
1 slice stale white bread
½ cup whole milk
2 tsp SIDS SALT & PEPPER
rice bran oil, for frying
WILD MUSHROOM SAUCE:--
1 tbsp rice bran oil
1 onion, chopped
3 cloves of garlic
500 g wild mushrooms
2 cups cream
SIDS SALT & PEPPER to taste
flat leaf parsley

Meat Patties
Preheat the oven to 200°C. Soak a slice of stale white bread in milk for 10 minutes.
Meanwhile combine ground pork and beef in a large mixing bowl. Process a medium onion in a food processor with two tablespoons of water until you have a paste or grate it using a vegetable grater, add to the mixture. Add soaked bread together with milk, SIDS SALT & PEPPER and mix well with your hands.
Scoop the meat mixture in a ⅓ cup and form an oval shaped patty, flatten it with a palm of you hand. Continue until all mixture is used up.
Heat the oil in a large frying pan and brown patties in batches to avoid overcrowding and steaming. Fry patties on both sides over medium heat for approximately 5-7 minutes, resist the temptation to flatten your puffed up patties for even cooking.
Put your browned patties in an oven proof pan in a single layer and cook in the oven for additional 10 minutes.
Wild Mushroom Sauce
While the meat patties are cooking in the oven, it's time to make the mushroom sauce.
Heat the oil in a saucepan and cook the chopped onion over low heat for 7-10 minutes, add minced garlic, and minced parsley stems but reserve the leaves for garnish. Add chopped mushrooms, SIDS SALT & PEPPER and cook for 10 minutes.
Add cream, bring to a boil, then reduce the heat to low and let it simmer for 5 minutes. Taste and add more SALT & PEPPER if necessary.
Blend into a smooth sauce in a food processor or a blender or leave it chunky.
Serve meat patties with hot wild mushroom sauce and sprinkled with parsley.
