The first step is to cut the "protagonists" into everything!

Chop purple onions as much as possible ~

Chop garlic as much as possible ~

Chop tomatoes as much as possible ~

Chop coriander as much as possible.

Grind the black pepper ~ Anyway, I like black pepper to be heavy and spicy, so I grind it a lot. If you don't like it too spicy, just moderate it!

I'm too lazy to cut tomatoes and break them directly with a cooking machine.

You can also beat onions and garlic with tomatoes on a cooking machine, so you don't have to cut them so much. (P: If you don't mind the smell of garlic and onion in the cooking machine, and would like to wash it more often)

The materials are ready, and I forgot to take pictures in the middle of the stir-fry?

Take the pan, add oil, and saute garlic, onion and coriander; Stir-fry until the onion is soft, just pay attention to a small fire during the process.

After saute, add tomato juice and medium heat.

Add a bowl of water, freshly ground black pepper, oyster sauce, soy sauce and salt.

When it's almost cooked, thicken it.

This process should be mixed constantly to prevent the bottom from being burnt.

Ok ~ the fragrant and thick black pepper sauce is ready!
