Place tomato slices in a single layer on a baking sheet or in a baking dish, season with a little salt and pepper, and drizzle with olive oil. Mix together the Parmesan cheese, Asiago cheese, bread crumbs and parsley; sprinkle over the tomato slices. Drizzle a little bit more olive oil over the top.
Broil for 5 minutes, or until the top is golden and toasty.
