This is super easy... also smells and tastes wonderful!
So... thaw out your Tilapia and pat dry with paper towels and place on a piece of aluminum foil, sprayed with Pam or whatever cooking spray you use... and then drop a dollop of sour cream on each piece of fish and smear it all over the top
Then sprinkle with Parmesan or a Three cheese blend which is what I use
Next sprinkle the fish with crushed Ritz crackers!
and then sprinkle lightly with oregano and bake at 350 degrees for approximately 20 minutes
Enjoy the smell while it cooks lol and then dig in!
