Steps
- Preheat the broiler. Drain 140g of canned tuna in water and flake into a bowl with 1 finely diced celery stalk and 1 sliced scallion.
- Mix in ⅓ cup of mayonnaise, 1 teaspoon of Dijon mustard, and ½ teaspoon of lemon juice. Season with salt and pepper.
- Split 2 English muffins and place cut-side up on a baking sheet. Broil for 2-3 minutes, until lightly browned, then remove.
- Set the oven to 400°F / 205°C. Divide the tuna mixture over the muffins and sprinkle with 55g of shredded cheddar.
- Bake for 10-15 minutes, until the filling is hot and the cheese has melted.
