For additional flavor you can add some herbs, such as oregano, thyme, or rosemary to this roasted tomatoes and onions recipe. I decided to keep this recipe simple because I love the flavor of tomatoes and red onions on their own.
Cherry or grape tomatoes work well in this dish, and I especially like the little “pop” of the tomato when you bite into it. However, I have made this recipe with cut up plum, or whole slicer tomatoes, as well.
Not a fan of tomatoes? Try roasting peppers, zucchini, eggplant, beets, carrots, kohlrabi, or potatoes instead. The sky really is the limit for the type of vegetables you can add to this roasted dish.
