I drizzled a little olive oil on a baking sheet, then some balsamic vinegar, and honey, I laid down some sweet onion slices, then a half a piece of raw bacon on top of that, then some thinly sliced gruyere. I took my thawed puff pastry and cut into 6 equal rectangles and laid it over the top and used a fork to go around the edges and seal it around the goodies underneath. I brushed it with egg wash (eggyolk plus 1 tbsp water) and baked at 400 degrees for about 20 minutes
