All afternoon during the latter part of the fast day we wish people "Beis Gut An" - break your fast well (i.e. don't be stupid and gorge yourself within the first 5 minutes, causing a decidedly uncomfortable bloated feeling followed by all night reflux....).
Some people break their fasts on the same foods fast after fast.
Others like to mix things up a bit.
I fall into the former category.... an everything bagel with scallion cream cheese, tomato, red onion and lox. I also cook up a pot of pasta (with or without creamy garlic sauce, depending on how many guests are coming).
What do you break your fast with?
