This version of the diner classic is enlivened with the tangy flavors of red pepper, lemon, and ketchup.

| 4 English muffins | 2 - 6 oz (170 g) cans albacore tuna, drained | |
| 1 tbsp olive oil | 2 tbsp ketchup | |
| 1 red bell pepper, seeded and finely chopped | 6 tbsp mayonnaise | |
| 4 scallions, white and green parts, thinly sliced | Grated zest of 1 lemon | |
| 2 shallots, finely chopped | 4 large, thin slices sharp Cheddar cheese, halved diagonally |
Position a broiler rack 6 inches (15 cm) from the heat and preheat. Split the muffins and toast.
Heat the oil in a small frying pan over medium heat. Add the red pepper, scallions, and shallots. Cook, stirring often, about 3 minutes. Add the tuna, breaking up the chunks with a fork. Cook for about 1 minute, until the tuna is heated through. Remove the pan from the heat and stir in the ketchup, 2 tbsp of the mayonnaise, and the lemon zest.
Spread the remaining mayonnaise over the cut sides of the muffins. Spread 4 muffin halves with the tuna mixture and arrange the cheese triangles on top.
Grill until the cheese melts. Top with the remaining 4 muffin halves. Serve at once.
