This is a basic recipe and anything can be added to it. At the Fire station they call it "mystery meat" because they never know what is in it.
2 pounds ground beef
3/4 cups crushed crackers or dried bread crumbs
2 beaten eggs
1/2 cup finely chopped onions
1-8 oz can tomato sauce or ketchup
dash dried thyme
a dash of pepper seeds for spice.
1/4 cup mango salsa
