This is a tasty tomato side dish you can cook alongside roast chicken or pork.
Preheat oven to 350 degrees. Place tomatillos and tomatoes, cut sides up, on a rimmed baking sheet. Drizzle with oil, and sprinkle with coriander; season with salt and pepper. Toss to combine, then spread in an even layer. Bake until tomatillos and tomatoes are very soft and browned in spots, 45 to 55 minutes. To store, cover and refrigerate, up to 3 days.
