"When I have run out of ideas for ground beef I will often fall back on to a goulash (I don't know its real name) , tomato based with some sort of pasta shells..."
American Goulash, American Chop Suey, or Slumgullion are all common names for that.
Basically homemade beef-a-roni in a lot of ways.
I had a thread about it a couple of years ago when I rediscovered the recipe and started making it.
Mom made it when I was a kid and called it Goulash. I didn't appreciate it then, but I appreciate it now.
