Stir the onions for 2-3 minutes until they are almost cooked. Now add the carrots, zucchini and paprika strips and fry them for 5 minutes. Now cook the Chinese cabbage and bamboo shoots until the cabbage collapses.
Scatter the cashew nuts over the vegetables. Mix the rice wine, soy sauce, ginger, garlic, cornstarch and tomato paste and pour over the vegetables. Mix well and simmer gently for 2-3 minutes until the sauce thickens.
