At my house:

I go to the butcher because she would never buy steaks "that big".
I season and prepare the grill items.
I light the grill (charcoal only thank you very much)
I cook it, making sure it's done the way I like, usually by cooking extra, which I sample while cooking.
I yell into the house (like Sam Elliot) "5 minutes. Steaks are done in 5 minutes." so that everyone will be at the table when it's served so we don't eat it cold.
I do sometimes prepare the sides, especially the mushrooms and the like.
I select and open the wine.
I do help with dishes because it's the right thing to do. She already does just about everything else to keep the house from falling down around our ears.
Honey, you're my hero. (in case you're reading this)
