For the champagne risotto, finely chop the shallots and sauté in hot olive oil with the rice until translucent.
Pour in sparkling wine and let it evaporate while stirring constantly. Add the hot soup ladle by ladle.
Let it boil down again and again, stirring, until all the soup is used up and the rice is al dente (15-20 minutes).
Drain asparagus and cut into pieces, cut salmon into pieces as well. Stir Parmesan into the hot risotto and season with salt.
Carefully add the salmon and asparagus and serve the risotto immediately.
