Preparation

• Position a rack in the center of the oven, and heat the oven to 400°F. On a small rimmed baking sheet, toss the tomatoes with 1 Tbs. of the oil, 1 tsp. salt, and 1/2 tsp. black pepper. Bake until the skins crack, about 15 minutes. Set aside.
• Heat the remaining 3 Tbs. oil in a large, deep skillet over medium heat until shimmering. Add the pepper flakes and stir. Add the garlic and cook, stirring, until fragrant, about 30 seconds. Reduce the heat to medium low. Add the green beans and soy sauce. Stir to coat the beans, cover, and cook for 5 minutes. Uncover and gently stir in the tomatoes. Cook until the beans are crisp-tender, about 5 minutes. Season to taste with salt and black pepper. Serve warm or at room temperature.
