fresh grated Parmesan cheese (optional)
low fat mozzarella
balsamic vinegar (optional)
salt and pepper
Heat your oven to 375 degrees.Cut the zucchini into rounds about 1/3 inch think. Quarter or eighth the tomatoes depending on how big they are. Spread the zucchini and tomatoes on baking sheets. Chop up the basil and garlic together--with a little salt if you want the resulting paste to be finer.
Spread a little of the basil-garlic paste on each tomato. Drizzle the tomatoes with the olive oil and also the balsamic vinegar if you so desire. Sprinkle the zucchini with the Parmesan cheese and salt and pepper to taste. (You won't need much salt, if any at all). Drizzle the zucchini with olive oil.
Roast for about 45 minutes. The tomatoes should have crispy bits and the zucchini should be cooked completely. It smells divine when it is cooking.
Serve the tomatoes with a small slice of mozzarella. I like to put the cheese on right after it comes out of the oven so it has a chance to melt a little before serving. I think the cheese adds a nice creamy texture and cuts the bite of the vinegar, I don't consider it optional on the tomatoes.
I would say the serving size for a lunch is about half of a large tomato and a whole medium zucchini per person (if you like zucchini that is).
