Green Beans with Caramelized Onions and Bacon

We had someone bring a dish like this last year to our house for Thanksgiving.  It was really good that I searched the internet for a recipe.  I made it this year for Thanksgiving at our neighbors and it was a hit.  They were so good.  This dish will now be on our Thanksgiving menu for each year to follow.  I also am not a huge fan of onions, but once they are caramelized and with the green beans, they are delicious.  Hope you make them and enjoy them like we do.

8 oz. Bacon, chopped into 1" pieces
12 oz. Green Beans
1/2 Onion, thinly sliced
3 TB. Sugar
1/2 tsp Kosher Salt
1/4 tsp. Black Pepper
3 TB Apple Cider Vinegar

1. Cook bacon until crisp in a skillet.  Set aside.  Reserve bacon grease.
2. In skillet with bacon grease  saute onions with sugar, salt, pepper, and apple cider vinegar until tender. Set aside.
3. Steam or blanch green beans until tender and toss with onion mixture and reserved bacon pieces (i just cooked my green beans like I normally do which is to boil them for 7-8 min, or until tender).  Serve warm or at room temperature.
