FANTASTIC! A great side dish for just about any meal. Save this recipe for when your tomatoes in the garden are ripe and luscious! (or if you have a Farmer's Market, get them from there). First made this in 2009, and have used large cherry tomatoes instead of plum tomatoes and they were great too...good tomatoes for this are a MUST! I have also added about 1/2 cup Gruyere cheese along with the 1 cup of parmesan on the top for a real cheesy treat! Any rustic bread will do, but make sure you cut it in the 1/2 inch dice. Also, use fresh Parmesan cheese, it really makes a difference. It's VERY important to get it into the oven as soon as possible, else it may end up a bit soggy.
