I made this the other night and even Brian, who isn't a big fan of tomatoes, really liked it. It's a Barefoot Contessa recipe and it was a hit!
Slice Roma tomatoes into discs and drizzle with olive oil. Sprinkle with salt, pepper and dried oregano. Roast at 450 for 12 min. Then place a dollop of pesto on top and some grated Parmesan cheese. Roast an additional 10 min or until they are golden and bubbly.
