1
Two king oyster mushrooms, cut into 1cm square dices, and soaked in hot water for a while
2
I use pre-flavored diced beef. If using fresh beef, cut it into small pieces, then add salt, starch, and black pepper to marinate for a period of time
3
Mix the beef cubes and king oyster mushrooms evenly, add a little cooking oil, and then place them flat on the rimless baking sheet
4
If there is hot air in the oven, set it to 160 degrees for about 20 minutes. If not, then heat it up and down to 170 degrees for 15 minutes~
