Once your oven has preheated, pull the skillet out (carefully!! I can't tell you how many times I have nearly grabbed a 375* pan handle, forgetting that it has been heated in the oven! To prevent this, I usually leave the oven mitt over the handle, so even if I do grab it, I won't burn myself...)
Now, dump your dough/mixture into the heated pan, smooth out the top as best you can, and slide it into the oven for 30-40 minutes. After the bread is finished baking, let it sit in the pan for about 5-10 minutes before cutting into it.
