Blueberry-Balsamic and Sweet Mustard Salmon

I'm not big on seafood, but I do love me some salmon. Salmon also has many nutritional benefits:

"Salmon is low in calories and saturated fat, yet high in protein, and a unique type of health-promoting fat, the omega-3 essential fatty acids. As their name implies, essential fatty acids are essential for human health but because they cannot be made by the body, they must be obtained from foods."

Here's one way to prepare this amazing food:

three medium salmon fillets
1/4 cup balsamic vinegar
1/2 cup frozen blueberries
4 T brown sugar, divided - or you can omit 2 T brown sugar and use honey instead
1 T olive oil
3 T mustard

1) Make sure your fillets are thawed.
2) Combine the vinegar, blueberries, 2 T brown sugar and olive oil in a very small saucepan. Stir over medium heat for about 5 minutes. Allow sauce to cool.

3) Place fillets in a plastic bag. Pour in blueberry sauce.
4) Allow to marinate at least 4 hours and up to 4 days.
5) Cook in an oiled skillet over medium heat. Times vary depending on size of fillet.
6) While salmon is cooking, combine remaining brown sugar with mustard in a small prep bowl or cup.
7) When fillets are cooked, spread mustard glaze over top of fillet and serve immediately.
