Preheat the oven to 180 degrees. Place the salmon in an oven dish and drizzle with some olive oil, season with salt and pepper. Place the salmon in the oven for 20 minutes. Add the breads for the last 5 minutes.

Crush the avocados with the lime juice and season with salt and pepper. Mix all ingredients for the dressing (sour cream, mayonaise, mustard, honey).

Take the breads out of the oven, cut them in half lengthwise and brush with the avocado spread. Remove the salmon from the oven and pull the fillets into pieces, arrange them between the rolls. Arrange the salad in between, finish with the dressing and close the sandwiches.
