Cooking on 11th Wedding Anniversary

I used to take my wife out to expensive restaurants on our wedding anniversaries.  This year, I told my wife that I'll cook for her on our 11th wedding anniversary coming up next weekend.  This is a big deal for me because, raised in a traditional Korean family, I have never cooked in my entire life.  So I am googling for easy yet memorable receipies when I can.  This is going to be quite an adventure.  If you have a good suggestion, let me know.  Yes, I do have a barbecue grill that I let my wife use all the time.
