yellow onion, chopped
parsley, fresh and chopped
white bread, firm, crusts trimmed, diced
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 crumbled 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.
Cut into thick slices and serve immediately.
