My husband loves this zesty Southwestern-style fish. You can make it with any of firm whitefish–like cod or halibut–if tilapia isn’t available. You can even use boneless, skinless chicken breasts. I usually make a package of red or black beans with rice to serve with it while the fish cooks. If you have any leftovers, they make great fish tacos.
Preheat oven to 375 degrees F (190 degrees C). Grease a baking sheet with cooking spray.
Combine the chipotle pepper, adobo sauce, salsa, and 1 tablespoon lime juice in a blender and blend until smooth; brush the mixture over both sides of each tilapia fillet.
Spread the crushed tortilla chips into the bottom of a deep dish; dredge the coated fillets in the chips to coat. Arrange the fillets on the prepared baking pan.
Bake the fillets 15 minutes; turn and lightly spray with cooking spray. Continue to bake until golden brown, another 10 to 15 minutes.
While the fish bakes, place the avocado, sour cream, and 1 tablespoon lime juice and blend until smooth. Stir in the milk 1 tablespoon at a time until the consistency is similar to ranch dressing. Season with salt and pepper. Spoon the sauce over the baked fillets to serve.
