Before you begin, preheat your oven to 450F/232C and line a baking sheet with parchment paper.
To start, activate the yeast by mixing, in a small bowl, warm water, yeast and sugar. I usually give it a little stir, then let it sit for 5-10 minutes until it becomes frothy.
Make the dough by adding flour, baking powder, salt and olive oil to a mixing bowl.
Make a well in the middle of the flour mixture with your fingers and add the liquid yeast mixture.
Mix together with a wooden spoon, then knead for 8-10 minutes with your hands or the dough attachment on a stand mixer until soft and smooth. Add a spoonful of flour if too sticky, or a splash of water if too dry.
Place dough in a slightly oiled large bowl (or you can leave it in the mixing bowl of your stand mixer. Cover with a damp cloth or plastic wrap and set in a warm spot. Let it rise for 1 hour, or until the dough doubles in size.
While the dough is rising, make the filling by adding all the chopped filling ingredients to a medium bowl. Add date syrup and mix to combine until everything is evenly coated.
Once the dough has risen, punch down the dough with your fist, smooth it into a large ball and divide into 4 equal balls. Place on a lightly floured surface and roll the dough out into a cylindrical shape with a rolling pin until it's about 1/8 inch thick. To keep dough from sticking to rolling pin, coat it lightly with flour.
Add 2 tbsp of filling to the center of the dough and fold over like a dumpling, pinching the 2 sides together.
