It's always a hit at the Christmas party! It also works for many other occasions.
I don't know where the name comes from, but there's no actual groundhog.
1 pound hamburger
1 pound sausage
1 block of Velveeta or store-brand equivalent
1 large or 3 small cans of mild Rotel diced tomatoes and green chilis
Brown the ground beef and sausage (don't drain)
Put everything in a slow cooker
Heat until cheese melts; stir to combine
Great with tortilla chips!
