Balsamic Glazed Salmon

Ingredients
2/3 C Balsamic vinegar
3 Tbs brown sugar
2 Tbs whole grain Dijon mustard
1/2 tsp sea salt
2 green onions, chopped
6- 6oz  salmon fillets, skinned

Directions
In a large zip top bag, add the Balsamic vinegar, brown sugar, Dijon, salt and green onions. Mush to combine. Add the salmon to the zip top bag, seal tightly and turn to coat. Place in a shallow dish and refrigerate for 2 hrs, turning after 1 hr.
Preheat oven to 400 degrees. Remove salmon fillets from the zip top bag. Place on a rimmed baking sheet and bake in the oven for 15-25 minutes, until the fish flakes easily with a fork. While fish bakes, pour remaining marinade in a small sauce pot. Bring to a boil, reduce heat and simmer until reduced by half and thick.
Once fish is cooked through, brush with glaze and garnish with more green onion (green tops only).
