Ingredients



- 2 slices sourdough bread
- 1 tablespoon salted butter, soft enough to spread
- 90g canned tuna, drained well
- 1 tablespoon whole egg mayonnaise
- 1/2 teaspoon Dijon mustard
- 1-2 tablespoons red onion, finely chopped
- Freshly cracked black pepper, to taste
- Zest of 1 small lemon
- Small handful fresh parsley and chives, finely chopped
- Small handful of grated sharp cheddar cheese (I've used a Red Leicester)
Method
- In a small bowl, combine tuna, mayo, Dijon mustard, red onion, herbs, lemon zest, and black pepper. Mash with a fork until well mixed.
- Spread softened butter on one side of each slice of sourdough bread, then turn them over, so the butter is on the outside.
- Now spread the tuna mixture evenly onto one slice of bread, covering to the edges.
- Sprinkle the grated cheddar cheese onto the other slice of bread.
- Carefully place the two slices of bread together to form a sandwich.
- Heat a small frying pan over medium heat.
- Once hot, place the sandwich in the pan, buttered side down.
- Cook until the bottom is golden brown and crispy.
- Flip the sandwich and cook until the other side is golden brown and the cheese is melted.
- Remove from the pan and let it cool slightly.
- Slice the sandwich in half and serve hot.
NOTES
- To ensure proper melting of the cheese, allow the sandwich to cook over medium heat until both sides are golden brown and the cheese is melted.
- Keep an eye on the sandwich while frying to prevent burning. Adjust the heat as needed to ensure the bread doesn't cook too quickly.
- Sourdough bread adds great flavour and texture, as well as holding up to the substantial filling, but you can use any bread of your choice. For a gluten-free option, use gluten-free bread.
- Taste the tuna mixture before assembling the sandwich and adjust the seasoning if needed. Add more salt or pepper to suit your taste preferences.
- I like to use a sharp cheddar cheese in a tuna melt; I love the tangy flavour and contrast it provides. But feel free to use your favourite cheese if you prefer.
- This sandwich is best enjoyed fresh, but you can prepare the tuna mixture in advance and store it in an airtight container in the refrigerator for up to 2 days.
