Combine the ground meats, onion, bread crumbs, parsley, ketchup, mustard, 2 eggs, thyme, salt and pepper. Spread the mixture out on a large piece of waxed paper or parchment paper into a rectangle about 15 x 12".

Pour scalded cream over the bread in a medium size bowl and mix well. Add cheese and lightly beaten egg and beat with a fork until smooth. Spread the cheese mixture over the meat mixture, leaving a 1" border on all sides. Using the waxed paper as an aid and starting from one short side, roll up the meat like a jelly roll. Peel back the paper as you roll. Place seam side down on a foil-lined baking sheet. Bake 1 hour at 375 F. Cut into thick slices and serve immediately.
