Drain the pineapple and reserve 2/3 cup juice.
Stir the pineapple chunks, cucumber, red pepper, red onion, vinegar and hot pepper sauce, if desired, in a medium bowl.
Heat the broth, wine and reserved pineapple juice in a 12-inch skillet over medium-high heat to a boil. Add the fish to the skillet. Reduce the heat to low. Cover and cook for 10 minutes or until the fish flakes easily when tested with a fork. Serve the fish with the pineapple salsa.
