Crush up a bunch of Triscuit crackers. Stir in a tablespoon or two of corn meal. Spread on a shallow plate.
In a bowl, make a thick batter from the Bisquick mix and beer.
Dip the fillets in the batter then dredge in the Triscuit mix and place on a clean plate until all the fillets are coated.
In a large skillet, cast iron preferred, heat about 1/2" of oil over medium-high heat.
Add the coated fillets to the hot oil. Fry until golden brown turning 3 - 4 times.
Drain on paper towels.
Salt to taste and enjoy!
