This succulent roasted mushroom burger is so full of flavour and umami it’s as delicious as a good beef burger to me. With a thick layer of melted mozzarella, it will make any meat lover feel utterly satisfied.

* Cooks notes ~ This recipe could not be simpler and you need little else other than the pesto which already has all the flavour components. The Greek Pesto worked brilliantly with this recipe. I love to butter the burger buns and then toast them on a griddle pan. It gives them a wonderful toasty taste and crunchy texture. If you are fond of heat, you could either add a sprinkle of dried chilli before roasting the mushrooms or a splash of your favourite hot sauce afterwards.
