Add 2 Tbsp of bacon grease back to pan, whisk and add in 6 eggs and scramble. Add other filling ingredients and combine.
Once combined, line a cupcake pan with papers and divide the filling into 10 equal cupcakes. Top each with 1-2 Tbsp of cheese. Place in freezer to set. (this makes assembly easier).
In a machine, whisk egg, oil, sugar, water, 1 cup flour and salt until flour is smooth. Change to a dough hook and add the flour and yeast. Let knead for 5 minutes until dough is smooth.
Let rise for 1 hour in a greased bowl, cover with saran wrap.

(makes about 9 or 10) flatten out a piece of dough, making sure the edges are thinner than the middke and place one of the frozen fillings cfheese side down in the middle of the dough. Fold the dough up around the filling, pinch to close and lay on baking sheet pinched side down.
