Thaw the frozen vegetables and the frozen vegetables.
In a small saucepan, melt the butter and add the olive oil. Fry the flour for a couple of minutes. Add the remaining ingredients and give a good mix. Just cook until thick. Set aside.
Toss the bread crumbs and spices.
Preheat oven to 180 degrees. Keep a large baking pan ready.
Spread the chicken and the vegetables all over. Drop the sauce in random places all over.
Spread sufficient mozarella cheese. Sprinkle the bread crumbs over it and then sprinkle the dried parsley.
Bake for 20-25 minutes till the cheese is melted.

Notes
I spiced the bread crumbs with Creole seasoning. You can use Italian seasoning, salt and pepper. It is only to add an extra layer of flavoring.
