Simple Salisbury Steak

This is one of those American dishes that just makes for amazing comfort food. This is my take on it, I've kept it nice and simple whilst, hopefully, still having plenty of substance and flavour.

For the 'steaks' you will need:
500g minced beef
50g bread crumbs
1 small onion, finely chopped
1 egg, beaten
pinch of salt and pepper
1 tsp vegetable oil (rapeseed oil)

For the sauce you will need:
1 medium onion, roughly chopped
100g mushrooms, roughly chopped
2 cloves of garlic, crushed
2 tsp of butter (if needed)
2 tbsp plain flour
500ml beef stock
2 tsp worcestershire sauce
pinch of pepper

Method:
1. Add all the ingredients for the 'steaks' into a large bowl and mix, with your hands, until just combined. Do not over mix.
2. Divide the mix into 4 equal portions and form into oval shaped patties.
3. Warm the oil in a heavy frying pan over a high heat, add in the patties and cook for about 1 minute.
4. Turn the patties and cook for a further minute before removing from the pan and setting aside.
5. Add the onions and mushrooms into the pan and cook for 2 - 3 minutes.
6. Turn the heat down to medium, add in the garlic and cook for 1 minute.
7. If there's not a lot of oil left in the pan, add the butter and allow it to melt.
8. Once the butter has melted, add the flour and cook for 2 minutes stirring constantly.
9. Gradually add the beef stock, a little at a time, stirring constantly.
10. Stir in the worcestershire sauce and a good sizes pinch of pepper before adding the 'steaks' back into the pan and cooking, stirring occasionally, for about 5 minutes.

Notes:
Remove the steaks from the gravy and plate up with a good portion of mashed potatoes and steamed vegetables before spooning the gravy over the top.
