Bacon and Blue Pinwheels

It's that time of year and I'll be posting a lot of appetizer recipes because that's how I roll.  Tis the season for finger foods, Christmas parties, drop in's & pop by's. 
I made these last night so I could toss them in the freezer and have them for our Christmas party in a couple of weeks.  There are all things good in this recipe.  Blue Cheese or Stilton, caramalized onion and bacon.  It just doesn't get any better than that.  I came up with this moments before I began making them and boy am I glad I did.  They are super yum. 
If you do want to make them ahead, simply make them and roll them in foil unbaked, and then freeze them.  Let them thaw at room temperature for 10 minutes, slice them and then bake them as directed. 

Bacon and Blue Pinwheels

Makes between 30-40
2 packages of Puff Pastry, thawed
5 slices of bacon
1 large onion, quartered and sliced thinly
pinch of thyme
1 tbsp real Maple Syrup
Salt & Pepper
Blue Cheese (depends on how much you want, 4-5 tbsp works well)
Fresh Parmesan (optional)
1 egg, beaten

Cook the bacon until just crisp and set aside.  Drain all but 1 tbsp of fat and over low heat, cook the onion for about 30 minutes, stirring occasionally.  Season the onion with a pinch of salt and a pinch of thyme and the maple syrup.  Cook another minute or two.  Finely chop the bacon into a bowl and add the onion mixture.  Let it cool.
Roll out the thawed puff pastry into a 20x15 inch rectangle.  Cut it in half horizontaly, so you have 2 pieces. 
On the botton half of the puff pastry, spread a 1/4 of the onion mixture an inch high (remember you're spreading the mixture on the long edge).  Sprinkle with 1/4 of the blue cheese and a grating of parmesan.  Brush the top edge of the pastry with the egg. 
Roll up the pastry into a log, sealing the edge with the egg.  At this point you can freeze the rolls or simply slice into rounds and bake at 400 F for 15-20 minutes.
