In a bowl, mix the dough ingredients until you get a uniform dough. Sprinkle flour on your work surface and roll out the dough using a rolling pin to a thickness of about 1 inch. Use a cup to cut out circular shapes from the dough and place them on a baking sheet lined with parchment paper.

Preheat the oven to 355°F (180°C).

Heat olive oil in a pan and sauté the squash and garlic until the squash reduces in size, then remove from heat. Add the cheeses to the squash mixture and mix well. Take a teaspoon of the filling and place it in the center of each dough circle. Close the dough circles, shape them, and press them well. Brush with beaten egg and sprinkle some sesame seeds. Bake for 15-20 minutes until the borekitas turn golden and beautiful.
