When I roast a turkey, I put chopped apples, celery, and some onion in the cavity. I don't like stuffing. I prefer Corn Bread Dressing, which I cook on the stovetop. A friend in FL taught me about the apple stuffing; it gives a nice subtle flavor to the bird.
We would always put celery and onion in the turkey cavity. Didn't often roast chicken as they just weren't big enough. ;-)
I make cornbread dressing tonight, as we had leftover cornbread from earlier this week - turned out vey tasty. I baked it a little, just to make the edges crunchy. Mmm. Glad there are leftovers!
