Caramelised Onion, Mushroom and Goat's Cheese tart

A delicious tart . The caramelised onion were made by cooking down finely sliced onions for about 30 minutes, then adding sugar, balsamic vinegar and finely chopped garlic together with 100ml of water, and then cooked down. Mushrooms were mixed shitake and swiss brown mushrooms.

I used normal filo pastry, scored, and brushed the edges with egg. Just before serving, I drizzled a little bit of balsamic vinegar over the tart.
