Truffled mushroom burgers

Ingredients

• 4 portobello mushrooms, stalks trimmed
• 2 tbsp truffle oil
• 2 mini ciabatta loaves, halved (or 1 medium loaf halved)
• 1 shallot, finely chopped
• 4 tbsp mayonnaise
• (or veggie alternative) 25g parmesan or grana padano, shaved
• 2 small handfuls rocket

Method

1. Heat a griddle pan and brush the mushrooms all over with half the truffle oil. Season well with salt and pepper, then griddle for 5-6 minutes on each side until they are charred and tender.
2. Brush the rest of the oil over the cut sides of the ciabatta and griddle to lightly toast.
3. Mix the shallot into the mayonnaise and spread over the bases of the ciabattas. Top with the griddled mushrooms, followed by some parmesan shavings and rocket, and sandwich on the tops. Serve with skinny fries, if you like.
