Ingredients Youâll Need
Ingredients (Serves 2)

- 1 can (5 oz) tuna in water, drained
- 2 tbsp mayonnaise (or Greek yogurt for a healthier option)
- 1 tsp Dijon mustard (optional, for a tangy kick)
- 1/4 cup finely chopped celery
- 2 tbsp red onion, minced
- 1/4 cup shredded cheddar cheese (or your favorite melting cheese)

- 1 tbsp butter (for grilling)
- Salt and pepper to taste
- Optional add-ins: pickle relish, jalapeños, or a slice of tomato

In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, celery, red onion, and shredded cheese. Mix well until everything is evenly incorporated. Season with salt and pepper to taste. - Assemble the Sandwich
Lay out your bread slices and evenly distribute the tuna mixture between two slices. If youâre adding extras like tomato or jalapeños, layer them on top of the tuna. Top with the remaining bread slices. - Grill the Panini
