Cooking Frozen Mussels

I've never cooked or even bought frozen mussels before.
They're cooked and in a bag frozen in they're liquid.
The directions on the bag said not to thaw them but to
heat them in a soup pot along with some cooking liquid.
I added in some white wine, garlic and some tomato sauce.
This made a decent tasting clam sauce to serve with pasta.

Ingredients:
1 bag of frozen mussels
1 cup white wine
1 cup tomato sauce
1 teaspoon dried chives
1/2 teaspoon garlic powder

Directions:
Place frozen mussels in pot.
add in white wine, tomato sauce,
dried chives and garlic powder.
Cover pot and simmer until mussels are heated though.
Serve over a cooked pasta of your choice.
