For a deeper flavor, consider adding a pinch of red pepper flakes or a sprinkle of dried oregano to the vegetable mixture before roasting. Roasting time may vary slightly depending on the size of the cauliflower florets and the oven. Check for doneness by piercing a floret with a fork – it should be tender but not mushy. This dish is also delicious served cold or at room temperature, making it a perfect addition to a buffet or potluck.
