# How to Make:
01 - In a medium bowl, combine drained tuna, mayonnaise, Greek yogurt, diced celery, diced red onion, chopped Calabrian chili peppers, Dijon mustard, and lemon juice. Season with salt and black pepper. Mix until well blended and set aside.
02 - Lay out all four slices of sourdough bread on a clean work surface. Spread softened butter evenly on one side of each slice.
03 - Place two bread slices buttered side down on a work surface. Distribute half of the tuna salad mixture onto each slice, then layer two slices of cheese on top of each tuna portion.
04 - Cover each sandwich with a remaining bread slice, buttered side facing upward, pressing gently to secure all layers.
05 - Heat a large skillet over medium heat for 1 minute. Place assembled sandwiches in the skillet and cook for 3 to 4 minutes per side, applying gentle pressure with a spatula, until bread is golden brown and cheese is completely melted.
06 - Remove sandwiches from skillet to a cutting board. Drizzle each sandwich with Calabrian chili oil and sprinkle with fresh chopped parsley if desired. Slice each sandwich diagonally in half and serve immediately.
