Cut the fish into thin slivers and place in a shallow baking dish. Combine the juice, salt, pepper, vinegar, onions, and peppers in large bowl. Pour the mixture over the fish. Cover with plastic wrap and refrigerate for 2 to 3 hours. Turn the fish at least twice while marinating. Serve the fish in the same bowl along with smaller bowls filled with popcorn, potato chips, and cold sweet potato slices.
