In a large bowl, combine warm milk, sugar, and yeast. Let it sit for 5–10 minutes until it becomes foamy.

Add salt, olive oil, and flour gradually, mixing until a soft dough forms. Knead for about 7–8 minutes until smooth and elastic.

Place the dough in a greased bowl, cover, and let it rise for 1 hour or until doubled in size.

While the dough rises, mix the cheese, chopped peppers, tomatoes or ham, green onions, and seasoning in a bowl. Adjust salt and pepper to taste.

Once risen, punch down the dough to release air. Roll it into a rectangle (about 12x10 inches). Spread the filling evenly over the surface.

Starting from one long side, roll the dough tightly like a jelly roll. Cut into 10–12 slices using a sharp knife.

Place the rolls on a greased baking tray or in a round baking dish, leaving space between them for spreading. Cover and let rise for 20–30 minutes.

Brush the tops with beaten egg and sprinkle cheese or sesame seeds if desired.

Bake in a preheated oven at 375°F (190°C) for 20–25 minutes or until golden brown.

Remove from the oven and let them cool slightly before serving warm.
