Substitute any white fish, such as haddock, cod, or sole for tilapia in this recipe.
Preheat oven to 375° F. Lightly oil a baking sheet.
In a plastic or paper bag combine bread crumbs, Parmesan cheese, oregano (or Italian seasoning), salt and pepper. Hold the top of the bag shut and shake to mix everything together.
Pour vegetable oil into a small bowl. Working with one fillet at a time, brush both sides with a little of the oil, then drop into the bag with the bread crumb mixture and shake to coat well. Remove from bag and place on the prepared baking sheet. Repeat with the remaining fillets.
Bake for 10 minutes, turn fillets over and continue to bake for another 5 to 10 minutes, or until the fish flakes when you poke into it with a fork.
