If a recipe calls for a mild-flavored fish such as cod, you can easily substitute orange roughy or snapper. Bold-flavored fish, such as swordfish and tuna, are often interchangeable.

A Case for Frozen Fish
Today's high-tech method of freezing seafood quickly locks in both moisture and flavor, providing a top-quality selection of fish year-round. Many large supermarkets and wholesale clubs offer an excellent variety of vacuum-packed fish fillets and steaks at reasonable prices. Look for packages that are clean and tightly sealed, have no signs of thawed juices, and are free of ice crystals and freezer burn.
Fresh fish is not only healthy and delicious, it's as quick and easy to cook as a boneless chicken breast and almost as versatile. In fact, many of the same cooking methods used for chicken--broiling, grilling, pan-frying, and poaching--work equally well with fish.
A general rule is to cook fish for 7 to 10 minutes per inch of thickness (3 to 5 minutes per 1/2 inch). When done, fish will start to flake and, like a boneless chicken breast, will turn in color from translucent to opaque. To check for doneness, slip a small knife under the fish, and gently lift. When starting to flake, the fish will break open, revealing an opaque color throughout.
During these hot summer months, fish makes a fabulous topping for a main-dish salad. Cut your favorite fillets (we used tilapia, a mild, firm fish) into 2-inch pieces. Sprinkle with salt and pepper, coat lightly with vegetable cooking spray, and sauté in a hot nonstick skillet over medium-high heat 2 to 3 minutes or until fish begins to flake and is opaque throughout. Serve over mixed salad greens with your favorite dressing.
