Which vegetable is NOT commonly found in Porto's salads?

Potato is not commonly found in Porto's salads. Salads typically focus on fresh, crunchy vegetables that provide a range of flavors and textures, such as cucumbers, bell peppers, and cherry tomatoes. These vegetables are often used for their crispness and ability to add freshness to the dish. Potatoes, while nutritious, are usually used in more hearty or cooked dishes rather than in typical salad preparations, as they have a denser texture and a different flavor profile that doesn't align with the lighter, fresher concept of a salad.
