Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius).

In a bowl, combine the mixed grind with one egg, ketchup, 1/2 cup bread crumbs, one teaspoon garlic powder, one teaspoon onion powder, and salt and pepper to taste.

In a second bowl, combine the ground chicken with one egg, mayonnaise, 1/2 cup bread crumbs, one teaspoon garlic powder, one teaspoon onion powder, and salt and pepper to taste.

Sprinkle some flour on a piece of Gefen Parchment Paper. Roll out the pastry dough to measure 16 x 12 inches (40 x 30 centimeters). Spread the mixed grind mixture evenly over the dough. Arrange a single layer of beef fry over the meat layer. Spread the ground chicken mixture evenly over the beef fry.

Cut off the ends of the kielbasas and place them end to end in the middle of the dough, six inches (15 centimeters) from the bottom. Roll the dough just that the seams touch (not jelly roll style). Place the roll on a baking sheet seam side down.

Combine the last egg with paprika, making sure the paprika is completely incorporated, and brush it over the entire roll. Score the dough with your desired design and garnish with sesame seeds and parsley, if desired.

Place the baking sheet on the upper rack of your oven. Bake for one hour and 45 minutes. Lower the oven temperature to 275 degrees Fahrenheit (135 degrees Celsius) and bake for an additional hour.
