This pesto tuna melt is made on slices of sourdough bread with sharp cheddar cheese and fresh slices of tomato.
In a small mixing bowl, add the drained can of tuna, 2 tablespoons of Greek yogurt, and 2 tablespoons of pesto.
Mix the ingredients together until they are evenly incorporated and individual pieces of tuna are no longer visible.
Preheat the broiler on Hi and set out a large baking tray.
Spread the mayo onto the top sides of each slice of bread. Scoop the pesto tuna salad onto the slices of bread and spread into an even layer.
Arrange the slices of tomato onto the top of the pesto tuna salad. Sprinkle the grated cheese over the tuna mixture, gently pressing the cheese down with your fingers to ensure it sticks to the tuna.
Remove the pesto tuna melts from the oven and transfer to a cutting board. Drizzle the top of each toasted sandwich with a little olive oil, freshly ground black pepper, and flaky salt to taste.
Add the top slice of bread to each sandwich and slice in half, if desired. Enjoy!
