Let the glass noodles soak in warm water for about 10 minutes.
In the meantime, slit open the chilli pepper, clean, core, wash and finely chop. Peel and finely chop the garlic and ginger. Wash the chives and cut into fine rolls. Mix the chilli pepper, garlic, ginger and chives in a bowl with soy sauce, rice vinegar, Chinese spices, sesame oil and pepper to form a marinade.
Bring the salt water to the boil. Let the frozen vegetables and glass noodles simmer for about 5 minutes. Drain and drain well. Then mix with the marinade and let cool. Drain the tuna and chop it up. Mix with the glass noodle salad and serve immediately.
Tip: Depending on your taste, you can also add Chinese cabbage.
