Ohh, Bushee, Barb is right, you didn't give us many chances but I put mice-meat. The meat must be combination of beef and pork. That kind of a pie is very popular and delicious in Balkan, East Europe. We call that BUREK.
And let me tell you about summer nights after disco parties, all exhausted of to much dancing, starved, people go for a fresh baked BUREK and eat that while chatting and wait sun to arise...yeah, that were nights.
Ohh, other option is a pie filled with white cheese, eggs and leeks, very tasty, try that sometime, you will like that, I'm sure,
Ohh, I'm starving!
