In a large, rimmed baking sheet, spread the lard/shortening all over the bottom. Press one dough ball into a rectangle, reaching all four corners of the sheet, and let rest while you prepare your fillings (if you're using pre-stretched dough, place the frozen sheet onto the baking pan and let thaw)
In a large skillet, add 1 tbsp oil and cook ground beef until almost all of the pink is gone; add 2 tsp each salt, pepper and 1/2 the onion and cook until the onions are softened and the beef is cooked through. Remove cooked beef to another dish and add remaining oil to the pan.
Add the remaining onions to the pan and cook until softened; add your prepped greens and cook until all of the vegetables are soft (season to taste),
On half of the stretched out dough, add the beef mixture (making sure to scoop the meat up and drain most of the oil) and spread to cover half (leaving a border); top with greens (also drained because too much moisture will make a soggy crust), hot peppers (if using) and cheese slices to cover the filling.
Fold over the dough to enclose the filling and seal the edges by crimping and folding (see photo); brush with egg wash and sprinkle with sesame seeds and a touch of salt and pepper.
Heat oven to 400°F and bake until golden (remember, your filling is cooked, so you are just baking the bread!). Remove from oven and wait a few minutes (you might need your super powers for that one) before cutting and serving!
