Preheat oven to 350°F. Lightly grease 2 mini pie pans. Place bowls on a sheet pan.
In a large skillet, melt 2 tablespoons butter over medium heat. Add frozen vegetables and cook until they are tender, stirring occasionally. Stir in flour and cook 2 minutes, stirring constantly. Stir in Old Bay seasoning, sherry and cheese. Stir in half and half, and cook 5 minutes, or until thickened. Remove from heat and add shrimp, scallops and crab. Spoon into prepared dish.
Cover each crust evenly over each casserole. Top with melted butter. Bake for 20 minutes or until biscuits are golden.
Notes
Any combination of seafood can be used. We like to use any of the following:
shrimp, shelled and deveined
scallops
lump crabmeat, picked free of shell
lobster, shelled and deveined
fish fillet
clams
It's best to use raw seafood because it will cook completely during baking. Otherwise, it can become tough from overcooking.
