Caramelised Red Onion, Feta and Bacon Tart

Don't you just love a good tart? I certainly do and always make sure I've got some sheets of puff pastry stashed away in my freezer to quickly satisfy any tart cravings that may occur.

Part of the reason I love tarts is that they are a great vehicle for using up odds and ends. I know I told you last week that Frittata's were the mother of leftover vehicles...but tarts come pretty close too.

So, the tart in question involved slowly caramelising some sliced red onions in balsamic vinegar and brown sugar until sticky and syrupy, my house smelt amazing. Then all was required was some assembly work....unrolling out the puff pastry sheet, spreading over the onions and bacon and crumbling over the feta. So simple but so so tasty. Sun dried tomatoes and goats cheese would work well as an alternative, as would olives and grated cheddar. What are your favourite tart toppings?
