Suppose you were visiting friends and family in Ireland and your hosts decided to hold a lunch party in your honor and invited 10-12 people. What traditional recipes would be on the menu? I know each individual Irish cook would add his/her own twists and choices, but are there a few dishes that appear at just about all parties/functions? I've done some Googling on the topic but want to get beyond Colcannon and Soda Bread.
The reason for this query is that the Mrs. and I are hosting a St. Patrick's Day lunch and inviting some of our friends and family. We have Irish roots umpteen generations back, but we know next-to-nothing about them. I want to have a fairly "traditional" meal, but don't know exactly where to start. My initial thoughts were:
Colcannon
Soda Bread
Green (tossed) Salad
and that's as far as I got.

Is "Irish Stew" Irish?
Yes, there are regional differences in Irish cookery, but what dishes appear pretty much the island over?
Thanks for your help.
