turns out that if you have leftover mashed potato-rutabaga mix, and the end of a chunk of roquefort cheese and some fresh breadcrumbs because you had a cocktail party, you can use all these things to make a really tasty lunch.
i heated up the mash a little in the microwave, then put it into a gratin dish, crumbled the roquefort over, and sprinkled a light layer of crumbs over that. stuck it into the toaster oven on broil until I couldn’t endure the smell any longer and had to tuck in immediately. the fat from the cheese crisps up the crumbs, and the whole thing is amazing creamy goodness.
