Wash and clean the mushrooms thoroughly and let them drip off on kitchen paper. Wash and halve the tomatoes. Wash basil, dab dry and cut into fine strips except for a few leaves for garnishing.
Heat a large, coated pan. Leave bacon cubes in it until crispy, take them out. Heat butter in it. Add the mushrooms and fry them for about 3 minutes, turning them over. Add tomatoes and cook for about 2 minutes.
Fold in basil. Season with salt, pepper and a little sugar. Add stock and simmer for 2-3 minutes. In the meantime heat up oil in a pan. Fry the gnocchi for about 3 minutes while turning. Mix gnocchi and vegetables and arrange on plates immediately.
Garnish with remaining basil. Sprinkle with parmesan.
