Wash green cabbage, cale and broccoli. Dry with towels. Divide broccoli into inflorescences. Kale and green cabbage chop coarsely.
Put a piece of butter, chopped garlic, ground ginger and crushed red pepper in a pan.
When the butter has melted, fry the garlic for no more than one minute. Then add soy sauce and water. Cook another 30 seconds.
Add broccoli, green cabbage and cale. Mix with sauce, cover and cook over medium heat for 3-4 minutes.
After 3-4 minutes, the broccoli will still be crispy, but not too soft. It should be so. Mix again with the sauce and serve.
