Clean the chanterelles. Cook the pasta in salted water until al dente. Halve the onions and cut into half rings. Cut the bacon into strips.
Heat 2 tablespoons of oil and fry the sage leaves over a medium heat for 1 minute, then remove and set aside. Add 1 tablespoon of oil and stir-fry the onions and bacon for 3 minutes, then remove and set aside. Put another 2 tablespoons of oil in the pan and fry the chanterelles for 5 minutes.
Now mix in the bacon and onions and season with salt and pepper. Fold in the pasta and serve sprinkled with sage and parmesan.
