Baked Cod with French Creole Sauce

I love fish and try to make it for my family at least once a week. This is a great way to enjoy a nice piece of cod.  It's quick, easy and delicious.  It's also got a very nice kick to it.  I like to serve ours with mashed potatoes and salad/veggies.  Enjoy!
-olive oil cooking spray
-1 lb cod fillets (about 4 pieces)
-2 tsp extra virgin olive oil
-2 tsp Dijon mustard
-1/2 tsp salt
-1/2 tsp Creole seasoning
-1 Tbs lemon juice
-2 tsp dried parsley leaves
Preheat oven to 400 F.  Line a baking sheet with aluminum foil.  Coat foil with olive oil cooking spray.  Place cod fillets on top.
In a small bowl, combine remaining ingredients.  Divide mixture evenly on top of each piece of cod.
Bake in preheated oven for about 20 minutes.  Serve immediately.  Enjoy!
