check out Fofar Bridies. they're a Scottish pastry that usually calls for lamb but i've switched out beef or pork and throw in other veggies like potatoes and carrots.
Calzones are also a good one to check out. i used to make those while working for a restaurant years ago. we made 3 different types with the pizza dough we made: the 3 cheese blend we used for the pizzas along with ricotta and grated Parmesan cheeses, then spinach with the cheese mix, and the Works which was hamburger with onions, peppers, mushrooms and pepperoni and a little pizza cheese to hold it together.
