Sloppy Joes - an alternative recipe

Since some of the ingredients in the "simple sloppy joe" recipe may not be available everywhere, here's another one from Southern Living, 1982.  I like it equally as well and would recommend it. Happy cooking.

Sloppy Joes - Easy
        2 ½ pounds lean ground beef
        2 cups chopped onion
        1 (6-ounce) can tomato paste (1/2 of 340g can)
        ½ cup catsup
        ¼ cup tomato juice
        2 tablespoons Worcestershire sauce
        2 tablespoons prepared mustard
        2 tablespoons lemon juice
        1 teaspoon salt
        ¼ teaspoon pepper
Combine meat and onions in a large skillet; cook until meat is browned and onion is tender. Pour mixture into a colander and pat dry with a paper towel; wipe pan drippings from skillet with a paper towel.
Return meat mixture to skillet and add the rest of the ingredients; simmer 15 to 30 minutes stirring frequently.
To serve, spoon 1/2 cup meat mixture over each bun half.
