Take out the pastry and allow it to warm to room temperature, this will stop the pastry cracking
Pre heat the oven to 180 degrees celcius, gas mark 4.
Thinly slice your red onions and start to fry them in olive oil over a medium heat
Whilst the onions start to cook thinly slice your apples
Add the apples to the cooking onions and cook for about 10 minutes, until the apples are soft and teh onions are starting to caramelise
Whilst the mixture is cooking, roll your pastry onto a baking tray and cut into 4 equal rectangles
Put the pastry rectangles into the oven and cook for 6 minutes, this will stop the bases getting soggy when we top with the mixture.
Cut the bree into slices about 2cm thick
Once the pastry has cooked, remove it from the oven and place on a counter to be topped
Add the onions and apples into the center of the pastry rectangles
Top with a table spoon of your chosen chutney. I made two tarts with caramelized onion chutney and two with a pear and walnut chutney!
Top the mixture with the bree
Return the pastry to the oven for a further 5 to 10 minutes. Be careful not to allow the pastry to burn!
Serve and enjoy!
