Use the electric-grinder to a puree with mushrooms mixture, the egg and bread crumbs.
Add the pine nuts, thyme, pepper and salt. Refrigerate a few hours until the resulting dough is firm; then mold it with wet hands to form the 4 burgers.
In a pan with the rest of the oil, cold portions over medium heat 3 minutes per side, until they are golden; remove them from heat and keep warm. Sauté the bell pepper 3 minutes or until tender.
In a bowl, work the carrot, spring onions, the tabasco, mayonnaise and sour cream until a creamy mixture.

On top of this, place pepper strips and large shavings of Parmesan cheese. Complete the set with the other half of the roll.
