this was quick and easy. I think you might want to turn the oven temp down a bit, the bread browned on top too quickly and didn't get a chance to cook throughly all the way through. I added some sauted mushrooms, garlic and onion to the spaghettie sauce.
This is delicious and makes enough for a couple of meals so I hope it reheats well. I didn't have cannellini beans so substituted romano beans. I also used thyme instead of rosemary as I'm not a big rosemary fan. I will definitely make this again and hopefully next time I will have on hand some spaghetti sauce with mushrooms in it. I think that would really add to the dish!
