Ingredients:
- 12 oz (340g) High-quality tuna, thoroughly drained
- ½ cup (120ml) Quality Mayonnaise
- 2 Tbsp (30g) Finely diced celery
- 2 Tbsp (30g) Finely diced red onion
- 1 Tbsp (15ml) Fresh Lemon juice
- 1 tsp (5ml) Dijon mustard
- 1 tsp (5g) Sweet pickle relish
- ½ tsp Garlic powder
- ¼ tsp Black pepper
- Salt to taste
- 4 slices High-quality sandwich bread (Sourdough or sturdy white loaf)
- 4 oz (115g) Grated cheese blend (Mature Cheddar and Gruyère recommended)
- 2 Tbsp (30g) Unsalted Butter, softened
- 1 Tbsp (15ml) Mayonnaise (for grilling mix)
Instructions:
- Drain the canned tuna thoroughly, pressing out all excess liquid/oil. Flake the dry tuna into a mixing bowl.
- Add the mayonnaise, lemon juice, Dijon mustard, and relish to the tuna. Mix gently until just combined.
- Fold in the diced celery, red onion, garlic powder, pepper, and salt to taste. Do not overmix.
- In a small bowl, combine the softened butter and the 1 Tbsp of mayonnaise until smooth. This blend is for the exterior grilling surface.
- Spread the butter-mayo mix evenly and thoroughly onto one side of all four slices of bread. Flip two slices butter-side-down onto a clean surface.
- Divide the tuna mixture evenly between the two assembled slices (the non-buttered side). Spread it lightly, leaving about a half-inch border.
- Top the tuna filling generously with half of the grated cheese blend. Place the remaining cheese on the inside surface of the top bread slice.
- Place the remaining buttered bread slices (butter-side-up) on top of the filling, completing the two sandwiches.
- Preheat a skillet or griddle over medium-low heat. Place the sandwiches in the heated pan and cook for 4–5 minutes until the bottom is a deep golden brown.
- Carefully flip the sandwiches. Use a spatula to gently press down on the top of the bread, ensuring maximum contact with the pan.
- Cook for another 4–5 minutes, or until the second side is golden brown and the cheese is fully melted and oozy.
- Remove from the heat and let the sandwiches rest on the cutting board for one minute. Slice diagonally and serve immediately.
