To assemble the peppers, ladle your tomato sauce in a 9×13 baking dish (you may not need all of it, I had about a half cup left over). Next, working one at a time, take a pepper shell, season the inside with a pinch of salt, and then gently stuff (overflowing a little at the top if you’d like), and place, stuffing side up, in one corner of the sauce-lined dish.
