This is an old holiday favorite of my best friend's family. They make it every year. His family calls them pigs, but I think it is some variation of beef rouladen anyway, it's certainly delicious! I throw them in the slow cooker for about 5 hours instead of cooking them on the stove top for 3.
Cut up meat into 3/4" to 1" strips about 3 inches long. Pound strips to 1/8" thickness.
Lay out strips on table, springle lightly with pepper and onion salt. Cut bacon in half legnthwise and then about 2 to 3 inches long. Lay a piece of bacon on each strip of round steak. Roll each strip up, end to end fairly tightly and push toothpick through to secure.
Brown pigs in grease over medium high heat. (I use bacon grease)
Dice onion and cook in pot until slightly glassy and add sifted flour. Add water stirring slowly to start gravy.
Then put pigs back in pot. Add water to cover pigs and simmer 2 to 3 hours. Add flour or cornstarch to thicken gravy and kitchen bouquet to darken.
