Cauliflower can anchor a vegetable dish
The idea
Cauliflower has enough structure to remain recognizable in a cooked vegetable selection. Its surface can carry seasoning while the center provides a different texture. In a mixed vegetable order, the balance between cauliflower, eggplant and zucchini is worth checking rather than assuming every portion contains identical amounts.
A practical next step
If one vegetable is your favorite, ask about the current mix. Availability can affect the balance in a finished selection.
