Stir together the ricotta cheese, egg, salt and baking powder in the bowl of a stand mixer.
Gradually add in the flour with the mixer running over low speed, until the dough comes together. Then knead over med-high speed for 7 minutes adding in more flour if needed. (Dough should not stick to the sides of the bowl.) Refrigerate until needed.
Combine the filling ingredients and set aside.
On a lightly floured surface, form dough into a 14" log and slice into 9 pieces about 1 1/2 inches wide.
Roll out each piece into a 9-inch circle and fill one half with 2 tbsp of the meat filling. Fold in half and seal edges with a fork, dusting flour as you go to prevent any sticking.
Place chebureki onto a dusted tray and continue to work with the remaining dough.
Meanwhile preheat 1/2 cup of oil in a large skillet over med-low heat.
Fry chebureki for 3-4 minutes on each side or until golden and drain on paper towels to remove excess oil.
