Place a pizza stone or oven-safe nonstick skillet in the oven and preheat to 500°.
Put all ingredients (except meat and dough) into a food processor and blend until mixture is the consistency of tomato sauce.
In a large bowl, combine the meat and sauce and mix with your hands until well incorporated.
If using dough, divide it into 8 portions and roll out as thinly as possible, making sure each one singly fits onto the pizza stone or skillet that is in the oven (you can also use an inverted cookie sheet). Make the balls smaller if you must. You will probably need to cook the lahmajo one at a time.
Top each lahmajo with ½ cup of the meat mixture and spread it thinly over the dough. You can also add cheese at this time if you like. Using a piece of parchment paper or pizza peel, place the lahmajo into the oven and close the door quickly. Bake for 5 to 6 minutes. If the dough or meat mixture is still wet, bake 1 to 2 minutes more. (Note: Move quickly once you have the meat spread over the dough, otherwise it will add too much moisture and stick to the peel.)
Enjoy with toppings of your choice, or nothing at all (just a squeeze of lemon is most traditional). Cut into wedges and enjoy!
