Season tuna with salt. Cook tuna 5 minutes, turning once. Set aside to cool slightly.
Meanwhile, combine mayonnaise, red onion, dill and TABASCO® Sauce in medium bowl. Remove 1/4 cup to small bowl; stir in pickle relish to make tartar sauce. Set aside.
When tuna is cool enough to handle, break apart tuna with 2 forks and flake well. Add tuna to medium bowl with mayonnaise mixture; blend well.
Shape mixture into 4 patties, each about 3 inches in diameter. Sprinkle bread crumbs lightly on both sides of each patty. Broil patties 3 minutes on each side or until golden.
To serve, place each tuna burger on an English muffin half. Top with a tablespoonful of tartar sauce and a muffin half.
