The internet seems to say that New Englanders call it American Chop Suey, midwesterners call it goulash, and "other areas of the country" call it slumgullion.

More internet searching seems to suggest that the name "slumgullion" is western, from the Slumgullion Pass in Colorado.

Edit: nope, other way. Slumgullion Pass was named for the muddy landslide, which looked kinda like stew.

And a bit more internet searching tells me that "slumgullion" is a word that miners in the old West used for pretty much any dish made by throwing together whatever was available into a pot, and the meaning solidified around that particular mix of stuff during WWI.

We'd have ground beef with canned tomatoes, macaroni, whole black olives and canned corn (the recipe called for creamed corn but we never used that) mixed in and some cheddar cheese melted on top, which went by the name of Italian Delight. I though it came from the "I Hate to Cook" book, but I couldn't find the recipe in it last time I looked.

One of my favorite meals.

yes, we've had this conversation before. My mom called it Johnny Mazzetti and she used spices and also added veggies sometimes, like green peppers. I think maybe sliced green olives also and topped it with shredded cheddar. I still liked it.

American Chop Suey here, and delicious. I should make that sometime soon.

I dunno, with Cubans, the ground beef was used for picadillo--brown the ground beef, add the sofrito made with green peppers, onion, garlic, and Spanish olive oil, tomato sauce, tomato paste, some water or wine or whatever you have on hand, add raisins and olives (I don't do the olives) and some chopped pimientos, serve over hot, white rice.

No macaroni in evidence.

Johnny Mazzetti is what I've seen cafeterias call it. I don't think my mom ever made it, but if she did, it was probably Italian goulash or some such name.

I think my school called it hamburger helper.... that's what I think of it as.

Goulash here. My family adds cheese.
