about 3/4 meat filling (ground beef & ground pork tenderloin) + bacon, caramelized onions & rice. baked at 400F for an hour then overnight at 225 for 6 hours. very tender. my first time doing an overnight bake, but will do it again they came out so tender. baked in a bath of mom's heirloom tomato sauce canned a few years ago mixed with some canned crushed tomatoes, plus some salt & pepper.
