Peel and finely dice the onion and garlic. Heat oil in a pot, fry onion and garlic over low heat until transparent. Add rice and sauté briefly. Season with salt and pepper. Add broth and wine bit by bit, stirring from time to time.
Add the next portion of liquid only after the rice has absorbed the liquid. Cook for a total of 30-35 minutes. Slice the parmesan and stir into the rice, except for a little garnish. Leave to cool on a baking tray
Crush red pepper with a knife. Cut the cress from the bed and mix it with the pepper into the risotto, except for something to garnish. Put some risotto on each slice of salmon and roll it up from a short side. Arrange the rolls on plates. Garnish with the rest of the cress and Parmesan
