Sift the flour into a large mixing bowl, add the salt, and mix. This helps to achieve a smooth and even dough.
Dissolve the yeast in lukewarm water, then add it to the flour. Pour in the olive oil and start to combine the dough.
Knead the dough until it is smooth and elastic. If it is sticky, you can add a little flour, but not too much, as it may dry out the dough.
Place the dough in a lightly oiled bowl, cover, and let it rise for about 1 hour, or until doubled in size.
Meanwhile, wash the spinach, drain it well, and roughly chop it. Finely chop the garlic.
In a skillet with a little olive oil, sauté the garlic and spinach together until wilted, then set aside to cool.
In a bowl, combine the Greek yogurt with the grated mozzarella, spinach, and oregano to create a creamy filling.
Punch down the risen dough on a floured surface, then divide it into 4 equal parts and roll each into a circle.
Thinly spread tomato sauce on half of each dough circle, being careful to leave the edges free.
Spoon the yogurt-cheese-spinach filling onto the tomato sauce portion of the dough.
Fold the dough over to form a half-moon shape, press the edges together, then use a fork to crimp the edges well to seal them.
Place the calzones on a baking sheet lined with parchment paper, then brush them with beaten egg to give them a beautiful golden-brown color.
Bake in a preheated oven at 400°F (200°C) for about 20-25 minutes, or until golden brown.
Let the baked calzones rest for a few minutes, then serve warm.
