Cut the chicken or turkey breast or tofu into thin strips and fry in oil. Season with salt and pepper. First deglaze with vinegar. When it has boiled over, add the broth. Add mustard and tomato paste.
Then add the crushed broccoli and cauliflower to the hot soup and let it steep. The best thing to do is to switch the stove off or down. Don`t wait too long so that the vegetables stay nice and crisp and keep their color.
