I have used just about any meat I had left over and sometimes even diced up cold cuts. Of course, there's nothing wrong with just cheese. I usually mix whatever meat with a mix of cream cheese and shredded cheese (Mexican blend/Cheddar/whatever's in the house).
I have a go to meat, but I can't mention it until after Aug 20th - there's a "friendly ABT contest" with some Brethren and when they know my secret, they'll use it. :) LOL

And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified. [Acts 20:32 KJV]
