Ingredients
1 egg
1/4 cup chopped onion
1/2 to 1 teaspoon salt
1/2 teaspoon pepper
1-1/2 pounds lean ground beef (90% lean)
1 cup (4 ounces) pepper Jack cheese, divided
1 cup salsa, optional

Directions
In a large bowl, combine the egg, bread crumbs, onion, salt and pepper. Crumble beef over mixture and mix well. Press half of the beef mixture onto the bottom and halfway up the sides of a greased 8-in. x 4-in. loaf pan. Sprinkle 3/4 cup cheese over meat to within 1/2 in. of sides. Pat remaining beef mixture over cheese.
Bake, uncovered, at 350° for 50-55 minutes or until meat is no longer pink and a meat thermometer reads 160°. Sprinkle with remaining cheese. Bake 5 minutes longer or until cheese is melted. Let stand for 10 minutes before slicing. Serve with salsa if desired. Makes 6 servings.
