Russian Mennonite Bierock

They Originated in Eastern Europe, most likely Russia. 
The dish is common among the Volga German Community in the United States and Argentina.
The recipe was brought to the United States in the 1870's by German, Russian Mennonite Immigrants.
My wife's ancestry is German,Russian Mennonite.

NOTE: You can make your own homemade Dough recipe for Rolls or purchase Rhodes Frozen Bake and Serve Dinner Rolls, allow them to Rise in a warm place, according to package directions. Roll out each one and create a pocket for the filling. Just make sure that all sides are sealed well so the Filling doesn't leak out when Baked.

This recipe makes 8 Rolls.

Here are a few examples of what they can look like:

I use a combination of these Vegetarian Products.

Here's what you'll need:
Preheat the Oven to 350 degrees.
A Large Skillet
A Greased Sheet Pan or one Lined with Parchment Paper.

Filling:
2 pounds of Ground Hamburger Meat. (the Vegetarian version uses a Meat Free, Vegetarian Ground Round.) 
1 Large Onion, diced.
4 C Finely Chopped Cabbage.
2 tsp Salt
1/2 tsp Pepper
3 TBS Ketchup
A Dash or 2 of Tabasco Sauce.

In the Skillet on Medium High Heat:
Hamburger Meat 
Diced Onion
Cook until the Meat is Browned.
Drain the Grease from the Skillet
Reduce Heat to Low.

Add:
Cabbage 
Salt
Pepper
Ketchup
Tabasco Sauce

Continue cooking until Cabbage is limp.

Remove and allow to Cool slightly before filling the Dough.

Once the Dough has risen and is rolled out  divide the mixture evenly for 8 Rolls and
fill the dough, either pinching it together or Roll it in your hands to Form a Ball making sure all sides are sealed so the filling doesn't leak out during Baking.

Transfer them to the Sheet Pan.
Bake 20 - 30 minutes.

Enjoy!
Peace in the Kitchen!
