Clean the salmon fillet, rub it with salt and black pepper, and leave it for 10 minutes.
Heat a pan, add the olive oil, and fry the salmon until browned.
Mash the fried salmon into small pieces with a fork, sprinkle with a little ground black pepper, add the honey mustard sauce, and mix well.
Peel the avocado, remove the pit, and cut into small pieces. Peel the banana and chop it finely.
Mix the chopped avocado and banana, sprinkle with a little black pepper, add any salad dressing, and mix well.
Place the salad ring on a flat plate, put the mixed avocado and banana in it, and press down gently.
Cover the avocado and banana with salmon, press down and flatten.
Decorate with a little rosemary.
