The base for these tarts is onions, so caramelise one yellow and one red onion in some butter. Add some Madeira if you want (I always do).
Cut some store bought puff pastry to the desired size and start with a thick layer of the soft, sweet onions. Then add whatever you like. I made one with some beautiful Italian sausage and one with smoked ham. I also added some cherry tomatoes and fresh oregano. Be creative with what you've got, that's the fun part.
Brush the edges with some beaten egg and bake for about twenty minutes in a pre heated, 210C oven.
