Start by making dough. Take warm water in a jug and sprinkle some yeast and sugar in it. Let it sit for 5 mins till it gets foamy.
Take flour and salt in a mixing bowl and mix well.Pour this yeasty water over that and mix well. Drizzle with some olive oil and knead it well.
Now in a clean big bowl drizzle some oil. Place the dough over the bowl and cover it with damp cloth. Let it rest for 1 hour till it doubles in volume.
While the dough is resting, make the sauce. Heat oil in a kadai.Add in garlic and saute for a min. Add in tomatoes, salt, sugar, pepper, oregano, tomato ketchup and saute for 10 mins till it gets thick and jammy.Transfer this to a bowl and let it cool down.
Preheat the oven to 200 degree C/ 400 Degree F.
Now assemble the bites. Roll out the dough using some extra flour. Cut it into small squares. Spoon some sauce over the top of each squares. Add couple of cheese cubes, olives and fold them from all sides, so it forms a ball.
Place the ball on a well greased tray. Do this for the remaining squares. Once everything is done, drizzle with some oil and sprinkle some oregano over the top.
Now bake this for 20 to 25 mins till it is golden.
