1 tbsp Damson Plum Jelly
In separate frying pans, fry chicken tenderloins and mushrooms until cooked. Prepare buns by cutting in half and placing cheese on one half. Toast both halves of bun in oven until cheese has melted. Once toasted, remove from oven and spread mayonnaise and Damson jelly over the bottom halves of the buns. Layer chicken, mushrooms, tomato, and lettuce onto the bun and finish with cheesy bun lid.
