Preheat your oven to 350 degrees FWith a rolling pin, roll out all the slices of bread until flat (don't worry about the crusts, as they will most likely fall off) Here's what mine looked like:With a metal ramekin or another circle cutter, cut out 3 circles from each slice of bread.Save the extra bits in case the bread cracks and you need the extra for repair.Mist a mini-cupcake pan with oil.Press each bread round into one of the cups. Press in gently. Don't worry if it breaks, take a little of the extra bread to do a little patch work if needed.Lightly mist the bread cups with oil again, and bake in the oven for 10 minutes.Meanwhile, make the filling. In a medium bowl, mix together all the other ingredients.Remove the bread cups from the oven, add about 1 tsp of filling to each cup.Return the tarts to the oven and bake for 10-11 minutes until the cheese is melted and its puffed up slightly.Remove from the pan and place on a dish. Serve warm.Extra's can be frozen and re-heated at a later date.
