I usually just dehydrate bites of meat of various types, but when I'm in a mood:
1lb ground meat, type of your choice
2cups oatmeal (give or take, depending on the extras you use you mght need more)
From there add whatever you feel like, cheese, I'll sometimes grate in a little pepperoni, whatever.
Mix till its the consistancy of cookie batter. Blob onto a cookie sheet and smush the blobs kinda flat. 350 oven for 20 minutes, flip, cook till brown and crispy. Freeze whatever you don't expect to use in the next few days.
