Growing up at at home we called it "Spanish Hamburgers", don't know why or what makes it "Spanish". It is a very simple recipe and an alternative to canned Sloppy Joe sauce.
This is the recipe passed to me:
1 pound ground beef
1 can concentrated tomato soup
About 1 cup of ketchup (or a amount equal to the soup)
Brown the beef (drain excess fat) and add the soup and ketchup. Heat thoroughly. Serve on buns.
However, in my version, I will add:
about 1/2 cup chopped onions and 1 tablespoon of Worcestershire sauce to the ground beef. You could also add green peppers.
