Simple and fast, I often eat in the cafeteria when I was in college~
Cabbage washed and shredded, river powder (in vacuum packed) boiled in boiling water for two minutes, remove and drain
Put a little oil under the pot, sauté the dried chili with a small fire, then stir the cabbage under the stir-fry, and then the river powder.
Add salt and season with seasoning. When you eat, add some vinegar and chili oil~
Cabbage or other vegetables are fine.
