Again, very basic marinade. For the zucchini just olive oil, salt, black pepper and dried rosemary. For the grape tomatoes - olive oil, salt, balsamic vinegar, dried oregano. Bake both separately @ 400 for 20 mins. If you quarter the zucchini small enough they cook surprisingly fast. Might want to check them after 15 mins.
The tomatoes can go longer if you like that crusty reduction.
