Looking for a simple (beginner here!) but delicious recipe for a main course (potentially NY themed) to cook for my wife and her friend on Saturday (more information in the text)

My wife's best friend is coming over on Saturday to stay at our house for the night. My wife normally does all the cooking in our house apart from odd times when I've attempted it myself (if she's been poorly etc).

We are all going to eat together and her friend is just back from a once-in-a-lifetime trip to New York (she works in the local hospital and has saved up for 2 years for a 60th Birthday trip to the big apple).

I would like to give them a chance to catch up and relax over a bottle of wine while I cook something. I'd like something quite straight-forward so that I don't mess it up and something delicious as a treat (I did wonder about something New York themed in honour of her trip but that might be too ambitious?).

I have a tried and tested recipe for a peach melba for dessert but need a main course.

No-one has any allergies but my wife's friend isn't a fan of mushrooms. But, apart from that - anything goes.

Does anyone have any ideas? Even something I could prepare the day before would suit as I'm off work on Friday afternoon.
