One of my daughters and her husband are visiting and we had a quick entree tonight you may want to try - citrus salmon. You don't even need to marinate it! The citrus vinaigrette goes over the salmon while it cooks and you reserve some to serve.
The sauce for one pound of salmon: 1 t. green onion, 4 T. orange juice, 2 T. balsamic vinegar, 1 t. dijon mustard, 1 T. olive oil, 1 t. minced garlic, 1/8 t. salt, and fresh ground pepper to taste. Mix together and spoon over salmon. Bake at 450 for 12 minutes per inch of thickness or until cooked through.
Serve with some easy sides. (The recipe comes from my Hassle Free Dinners CD.)
