Ladies, I think the appropriate wine is MAD DOG!! (Sorry, couldn't resist!)
I would serve about a week or two of easy to cook, NOT gourmet, velveeta, cream of mushroom soup, or hamburger helper based meals. Something you can sling together in 20 mins, garnish nicely, and serve with cheap grape juice (Juicy juice?).
Then, if a try at a nicer meal gets a response, try a gourmet meal.
Serve what YOU want to eat, or let him cook for a while. At the same time, complement him on things. Nice shirt, thanks for all the hard work you do, yada yada yada.
I think a multi can approach will get the point across.
