Spread a layer of mayonnaise over one side of each piece of tsoureki. Then, sprinkle the mizithra evenly over the mayonnaise and press down firmly with your hands so that the cheese adheres to the mayonnaise.
2 teaspoons mayonnaise, 1-2 teaspoons grated dry mizithra, or grated parmesan cheese
Melt the butter in a frying pan. Place one piece of tsoureki into the frying pan, mayonnaise side down (in contact with the pan). Arrange your slices of feta evenly over the tsoureki. Drizzle with the honey.
1/4 cup (30 grams) feta, sliced thinly, 1 tbsp (15 grams) butter, 1/2 teaspoon honey
Place the second piece of tsoureki over the cheese, this time keeping the mayonnaise side facing up.
Cook over medium heat, flipping carefully so that both sides are a nice golden brown. It helps to use a spatula to also press down on the sandwich while it is cooking in order to help everything stay together.
When both sides of the sandwich are golden brown, remove from the pan. Cut your sandwich in half and serve.
Enjoy!
