In a large bowl, combine the flour, yeast, and salt. Add the olive oil and lukewarm water, and knead until you have a soft, non-sticky dough. If it's too dry, add a little more water.
Cover the dough with a clean kitchen towel and let it rise in a warm place for about an hour, or until doubled in size.
Slice the mushrooms, cut the bell pepper into strips, and chop the olives. Crush the garlic.
In a skillet, sauté the mushrooms, bell pepper, and garlic in a little olive oil for 5-7 minutes, until slightly softened.
Divide the risen dough into two equal portions and roll each into a circle, about 5 mm thick.
On one half of each circle, spread the tomato sauce, then sprinkle with the sautéed vegetables, olives, grated mozzarella, and Parmesan cheese.
Fold the other half over the filling and firmly press the edges to seal, preventing the filling from spilling out.
Preheat the oven to 400°F (200°C). Brush the top of each calzone with beaten egg to achieve a beautiful golden brown color.
Place the calzones on a baking sheet lined with parchment paper and bake for 20-25 minutes, or until golden brown.
Let them cool for a few minutes before slicing, to prevent the filling from being too hot and runny.
