Sautéed Beef Recipe

Melt the butter in a large frying pan.

Add the diced beef and sauté over high heat until it releases its juices and they evaporate.

Chop the onion and add it to the pan, cooking with the meat until the onions soften.

Sprinkle with salt, black pepper, and red pepper flakes.

Mix all the ingredients and cook for a few more minutes.

Serve hot. You can serve it alongside rice.
