• Remove from heat.
• Add bread crumbs, parsley, thyme, sage, mustard, salt and pepper; mix well.
• Set aside.
• PORK: Cut each tenderloin lengthwise halfway through; open like a book.
• Place between plastic wrap or waxed paper; using meat pounder or rolling pin, pound to generous 1/4-inch thickness.
• Cut about 7 pieces of kitchen string into 15-inch lengths; arrange crosswise about 1 1/2 inches apart in lightly greased roasting pan.
• Place 1 piece of meat on strings.

• Spread mustard all over roast.
• Arrange apple slices in lengthwise row on top; sprinkle with salt and pepper.
