Preheat oven to 375 degrees F
Cut each tomato in half vertically and place on a sheet pan
Drizzle with olive oil. Then sprinkle with garlic powder, italian seasoning, salt, and pepper.
Roast in the oven for 45 minutes then check to see if slightly browned on top, bubbling, and juices have run over and started to caramelize on the sheet pan. If not quite done, roast for another 10 minutes. Otherwise, remove from oven, serve, and enjoy!
