Preheat the oven to 350 degrees Fahrenheit with your pizza stone inside. Line a baking sheet with parchment paper.
Toss the 3 ounces of broccoli rabe with enough olive oil to generously coat, along with salt and pepper to taste.
Arrange in a single layer on the baking sheet. Roast at 350 degrees Fahrenheit until tender, 10 to 15 minutes. As soon as the broccoli rabe is done, remove the baking sheet containing it from the oven and turn the heat up to 550 degrees Fahrenheit.
Cut the 5 to 6 grape tomatoes in half from top to bottom.
