Salt and pepper the meat. Putting those in the crust or flour is not as nice.
Even if meat is preflattened, flattening it more more does not hurt and makes for a better end result.
Cheese last inside, don't do meat, cheese, then meat but meat, meat, cheese instead.

Also, ask anyone potentially participating if there's anything they don't want on it, e. g. vegetarians.
