4 (6-ounce) cod fillets (or tilapia)
- Preheat oven to 400°.
- Arrange fillets on a parchment-lined baking sheet. Brush 1/2 teaspoon mayonnaise over top of each fillet; sprinkle evenly with salt. Gently press about 2 tablespoons crushed chips evenly on top of each fillet. Cook fish at 400° for 10 minutes or until fish flakes easily when tested with a fork. Serve with ranch dressing.
