Especially delicious when served with fresh Parmesan shavings
Add onion to a frying pan and cook on medium to high heat until golden.
Add garlic and thyme and continue cooking for about 3 minutes on medium heat.
Throw in mushrooms and cook for another 10 minutes or so stirring occasionally.
One the mushrooms are done add some shredded mozzarella – it will melt as you stir it in.
Toast your bread or bruschetta, spread some butter on top and add a good layer of the mushroom mix. Top with some rocket & serve!
