Sprinkle salt and black pepper over steak and let it rest for 5-10 mins.

Heat cast iron skillet on a stove. Add in a little olive oil.

When skillet is very hot, lay steak in it. Fry each side for around 2 mins.

Cut in a small piece of butter. Also add in 2 or 3 cloves garlic and thyme.

Fry each side for 3 mins. At the same time, use a spoon to scoop melted butter and pour over the uncooked side.

Place steak in a plate and let it rest for a while.

Leave the rest oil in the pan. Put vegetables in skillet. I chose onion, asparagus and mushroom. Stir fry till vegetables turn softened. Add in 1/2 tsp light soy sauce, 1/2 tsp cooking wine and 1/2 tsp sugar. Stir fry for another 2 or 3 mins.

Dish vegetables out in a plate and cut steak into medium chunks and spread them over vegetables.
