Preheat over to 405*
Heat skillet and add bacon pieces, cooking until they are just about done, not fully
Remove the bacon from skillet with a slotted spoon and set aside
In a large bowl combine brussels sprouts, walnuts, bacon, salt and olive oil, toss to coat
Spread brussels mixture into a single payer onto baking pan, you may need two and put into oven
Add the balsamic vinegar to a small saucepan on medium and whisk constantly until the vinegar thickens creating a reduction, roughly 10 minutes.
After 20 minutes, add the raisins to the brussels, give the brussels sprouts a good stir and return to the oven for remaining 10-15 minutes.
The brussels sprouts should be browned on the edges with some crispy pieces scattered amongst
Once the brussels sprouts are done, plate and sprinkle goat cheese (optional) and drizzle balsamic reduction over the top
