Food in general is associated with anxiety, death or disaster.

- Carlo's chopping onions, I believe, just before he and Sil kill Big Dom.
- Tony steps on eggs before ordering the hit on Tony B.
- Ralphie is making scrambled eggs just before Tony kills him.
- Richie sits down to enjoy his meal just before Janice shoots him.
- Tony's panic attacks are at one point associated with raw meat.
- The brief exchange before Chris kills Emil Kolar: "In the Czech Republic too we love pork. You ever have our sausages?"
- Valentina is cooking eggs when she sets fire to herself.
- Livia's cooking mushrooms when her kitchen sets alight.
- Tony's eating onion rings in the final scene...

But then food also brings people together...

- Tony and his family seek shelter in Artie's new restaurant at the close of season one.
- Funerals loom large in the show; there's always a feast.
- Speaking of which, Junior finds particular comfort by attending the funerals of those to whom he's barely related; he enjoys the food more than anything.
- Vito's love affair in season 6A is with more than johnny cakes.
- Tony and Carmela's decadence, with their sushi restaurant...

There are tons more.
