Line a rectangular pan (6" x 14") with foil or wax paper. Spread the meat mixture (1st layer ingredients). Press and flatten evenly.
Spread second mixture on top of 1st mixture. Press tightly.
Then as in a jelly roll, roll up tightly and wrap in foil. Chill in a refrigerator for several hours or overnight.
Bake in a pre-heated oven, with 350 °F heat for 45 minutes or, steam-bake for 1 hour. You may serve whole or sliced thickly.
Make gravy out of the drippings. Thicken with 1 Tbsp dissolved cornstarch or flour.
