Interesting topic. I've recently moved away from my home town Chicago to Minneapolis and will say that yes, hot dish is a staple here. Maybe not to the younger generations but it's something that people think of fondly. Every fall, there seems to be countless news segments and articles written about hot dish but you'll rarely find it outside of someone's home.
Things I miss from Chicago, that is, things I've either eaten or prepared that I don't as much are:
-Italian sausage - grilled with peppers and onions or in a red sauce for either a pasta side or sandwich. I'm not Italian but I seem to have eaten this at least weekly and the Italian Sausage was a consistent grill item at most home / friend's parties. I can't find a decent I-sausage here. Everyone points me to the same sausage place in NE Mpls and although it's good, it's not the same as having dozens of retail options at your beck and call.
-Subs. Not Subway or Potbelly's but a good sub sandwich. Does not exist here but back in Chicago, people would buy huge subs for parties. Almost every b-day party had one in the western burbs. I remember eating cold cuts for dinner and it was a treat - fresh bread, good quality meats and cheeses and all the "trimmings." I recently suggested to my MN-born wife that we should just have sandwiches for dinner and she looked at me like I was crazy - "not for dinner! - only for lunch!"
-I could always find or knew someone that had/made a good red sauce. We make one, from scratch and it was passed down from my mom, from her mom, from her mom. Again, I'm not Italian but my Mom grew up around Italians in Maywood and Addison so her family picked up some ideas from neighbors. Have you ever suggested to anyone outside of Chicago to use neck bones for their "gravy?" They don't know what the hell you're talking about - maybe the East Coasters do.
-I know Tacos aren't "home cooking" but I make them here in MN at home more than seek them out. I go to one of the few Mexican grocers in South Mpls and buy skirt steak, chicken, house made salsas and crema. I use local, fresh tortillas and when I invite people over, they're pretty impressed. "Where did you get this stuff?" -I wouldn't say they're amazed but it's rare for them to eat "ethnic" food at home. For me, tacos a few times a week (especially after the bars) was routine, so I didn't have to make them at home as much. But I miss that access here.
-During Easter in Chicago, you would find a pound cake or butter shaped like a lamb. I don't see that as much here.
I don't want to dismiss pizza, hot dogs, or cheesecake. I know these are cliche but they are a fact of most people's diet in Chicago. Here's the deal when you move out of the city - delivery options are very limited. The idea of ordering a pizza on Friday night for dinner is not unique to Chicago but having more than 3 pizza options might be. Arguing over the toppings / deep vs thin / pizza place / etc seemed to happen in Chicago much more than here. You know what's popular in Mlps? - Papa Johns and a "local" place Pizza Luce that tastes just like Domino's. I basically have one option here and I get it every week because my 4 year old likes pizza once a week and I don't want to cook every day. I would kill for a Pequod's or even My Pie deep dish delivered to my door.
I'm sure I'll come up with more. I'll be checking back frequently to remind myself how much I miss Chicago food.
