In Spanish tapas cuisine, what is escalivada mainly made from?

In Spanish tapas cuisine, escalivada is mainly made from roasted vegetables.

The Catalan dish traditionally uses eggplant, bell peppers, onions, and sometimes tomatoes. The vegetables are roasted or grilled until tender, peeled when appropriate, and arranged in strips with olive oil and salt. It may be served on its own, with bread, or alongside meat and fish.

The name comes from the Catalan verb escalivar, meaning to roast over embers. This explains why grilled or fire-roasted versions are especially characteristic. Escalivada is sometimes treated as a salad, side dish, or tapa; its defining feature is the preparation of the vegetables rather than one fixed garnish.
