When the weather shifts towards a decidedly fall-into-winter temperature range, my cooking shifts too in an almost subconscious way. I like the way this makes me feel connected to the natural patterns of the world around me. The produce at the farmers market has been glorious of late: the deep greens of the lettuces, kales and their kin and the rich sunset-like hues of the tree fruits, winter squash and cruciferous clan. You almost can't avoid making a casserole or two and such was the impetus for this simple, satisfying bake.
