Roasted chicken is so easy that it's my go-to meal when I'm feeling too lazy to properly entertain friends. I throw it in the oven along with some new potatoes and let everything roast while I relax with a magazine and await my guests. They think it's a great meal and I'm not stressed from cooking some elaborate meal. (There's also fewer pots and pans to wash when that times comes.)
I'm thinking engagement chicken could only work on guys who haven't eaten much other than fast food, take out and suburban chain restaurant fare since leaving home for college. Maybe I'm wrong, but I just don't see anything that special and magical about roasted chicken.
