Step 1: Prepare the Tuna Filling

• In a medium bowl, combine drained tuna, mayonnaise, and Dijon mustard.
• Add lemon juice, garlic powder, onion powder, black pepper, and salt.
• Stir in chopped celery and red onion (if using) for extra crunch and flavor.
• Mix everything until well combined and set aside.

Step 2: Assemble the Wrap

• Lay a flour tortilla flat on a clean surface.
• Sprinkle ¼ cup of shredded cheddar cheese evenly over the center of the tortilla.
• Spoon half of the tuna mixture on top of the cheese.
• Add 2 slices of tomato and a handful of fresh spinach or lettuce if desired.
• Fold in the sides of the tortilla, then roll it tightly from the bottom up to form a wrap.

Step 3: Toast the Wrap

• Heat a non-stick skillet over medium heat and add 1 tablespoon of butter or olive oil.
• Place the wrap seam-side down in the skillet and toast for 2-3 minutes until golden brown and crispy.
• Flip and toast the other side for another 2-3 minutes until the cheese is fully melted.
• Remove from heat and let it cool for 1 minute before slicing in half.

Step 4: Serve & Enjoy

• Serve warm with a side of chips, pickles, or a fresh salad.
• Enjoy with a dipping sauce like honey mustard, ranch, or spicy sriracha mayo.
