Cheeseburger Meatloaf

1/2 cup ketchup, divided
1 egg
1/4 cup dry bread crumbs
1 teaspoon onion powder
1 pound lean ground beef (90% lean)
2 teaspoons prepared mustard
2 teaspoons dill pickle relish
6 slices process American cheese

In a bowl, combine 1/4 cup ketchup, egg, bread crumbs and onion powder. Crumble beef over mixture and mix well. On a large piece of waxed paper, pat beef mixture into a 10-in. x 6-in. rectangle. Spread remaining ketchup over meat to within 1/2 in. of long sides and 1-1/2 in. of short sides. Top with mustard and relish.
Place four cheese slices on top; set remaining cheese aside. Roll up loaf, jelly-roll style, starting with a short side and pulling away waxed paper while rolling. Seal seams and ends well. Place loaf, seam side down, in a greased 11-in. x 7-in. baking pan.
Bake at 350° for 45 minutes or until meat is no longer pink and a meat thermometer reads 160°. Cut the reserved cheese slices in half diagonally; place on top of loaf. Return to the oven for 5 minutes or until cheese is melted. Let stand for 10 minutes before slicing.

I think adding some crumbled bacon before rolling up the meatloaf, would be an excellent addition. I may try that the next time I make this. It is a hit with everyone at my house!
