Shrimp and Fish Pie with Four Cheese

Last week when I shop at local supermarket for my weekly marketing,I saw frozen pastry skin on sale !! I quickly grab 2 box and throw in my shopping cart. Frozen food have longer expiration date,so I like to stock whatever it's on sale but sadly my fridge is too full:(
When I'm lazy and no mood to cook elaborate dinner or lunch this frozen pastry skin is really handy and easy to use.I just put all the ingredients together and in less than hour we can have a scrumptious Seafood Chessy Pie !!
