Peel and wash the asparagus, cut off the woody ends. Cut asparagus into pieces of about 5 cm and cook in boiling salted water for 10-15 minutes. Clean the mushrooms, if necessary cut them into small pieces. Peel and finely dice onion and garlic
Fry the mushrooms and onion in 2 tablespoons of hot olive oil for about 4 minutes, turning them over. Season with salt and pepper. Drain the asparagus and let it drain. Cut tomatoes into quarters, remove seeds and dice the flesh. Cut chives into small rolls
Mix vinegar with salt, pepper and the rest of the oil. Add tomato cubes and chives. Turn asparagus and mushrooms in the tomato vinaigrette
Pluck the salad into bite-sized pieces. Arrange on four plates and arrange the lukewarm asparagus salad on top. A hearty rye bread tastes good with it
