You'll need a 24cm diameter flan tin.
Mix the carrots, oats and butter.
In a separate bowl, mix the flour, baking powder and salt then add to the carrot mix and combine to form a dough.
Press it into your tin and chill in fridge for 1/2 hour minimum.
Bake in a hot oven, 200C/gas 6 for 15 minutes.
Heat the olive oil in a large pan and saute the onions slowly till they start to caramelise.
Add the garlic and chopped chard stalks, and - a couple of minutes later - the chard leaves. Cook until the chard has wilted.
Put the chard mixture into a bowl and combine with the eggs, milk, parmesan, parsley, salt and pepper.
Pour into the tart crust and bake for a further 20 minutes at 180C.
