While pasta cooks, cut broccoli into smaller florets and place in a baking dish. Toss with olive oil, then sprinkle with salt, pepper, and bread crumbs. Bake for 20 minutes.
Drain pasta and return to warm pot. Add butter, cheeses, and milk; stir until melted and well combined.
Serve macaroni with broccoli and sliced peaches on the side.
