The Happy Pear know their way around a good pesto! The pesto they make in this recipe is a version of their favourite sundried tomato pesto which is amazingly versatile and any leftovers will go wonderfully with pasta or in sandwiches.


Makes 4 burgers.


  1.  To make the pesto, first soak the sundried tomatoes overnight. Alternatively, if you’re short of time, put them in a saucepan, cover with hot water, bring to the boil and simmer for 10 minutes until softened. Drain, then gently squeeze until dry.
  2. Add all the pesto ingredients, except the mushrooms, into a food processor with a pinch of salt and whizz until smooth. Don’t over blend – you want the pesto a little chunky so there is a little bite to it. Put half of the pesto into a mixing bowl and add the mushrooms. Mix well until the mushrooms are evenly coated in pesto.
  3. Skewer the mushrooms onto metal skewers, or bamboo skewers soaked in water. Put the mushrooms on a hot part of the barbecue and cook, turning regularly, until they start to char and smell amazing, probably about 5-7 minutes. Carefully remove from the skewers.
  4. Toast the giant baps. Add some vegan coleslaw and a few rocket leaves, then top with a decent portion of the pesto mushrooms. Add a couple of slices of avocado and top with the bap lid. Enjoy this next level barbecue sensation!
