Green Chile Tuna Melt Recipe

Drain and Flake Tuna

Open the canned tuna and drain thoroughly. Transfer tuna to a medium mixing bowl and use a fork to flake into small pieces.

Add mayonnaise, Greek yogurt (if using), and Dijon mustard to the flaked tuna. Stir until combined and creamy.

Fold in diced green chiles, red onion, celery, chopped cilantro, lime juice, salt, and black pepper. Taste and adjust seasoning — add more chiles or hot sauce if you prefer more heat. Set the tuna filling aside.

Lay out 4 slices of bread. Divide the tuna mixture evenly among them, spreading it to cover each slice but leaving a small border around edges to prevent overflow during grilling.

Evenly sprinkle shredded cheddar and Monterey Jack (if using) over the tuna on each slice. Add optional toppings if desired: one or two tomato slices or a few pickled jalapeños for extra tang/spice.

Top each assembled slice with the remaining 4 slices of bread to form sandwiches.

Heat a large skillet or griddle over medium heat. While it warms, spread butter evenly on the outer sides of each sandwich (both top and bottom).

Place two sandwiches in the skillet (buttered side down). Cook for 3–4 minutes until the bread is golden brown and the cheese begins to melt. Press gently with a spatula to help the sandwich compact and heat evenly.

Carefully flip the sandwiches and cook the other side another 3–4 minutes until golden brown and cheese is fully melted. If the bread is browning before the cheese melts, lower the heat to medium-low and cover the skillet with a lid for 1–2 minutes to trap heat and encourage melting.

Remove sandwiches to a cutting board and let rest 1 minute, then cut in half diagonally.

Serve each Green Chile Tuna Melt hot, optionally with extra lime wedges, hot sauce, or pickled jalapeños on the side. Pair with a simple green salad, chips, or tomato soup.
