What is the primary ingredient of the traditional American dish succotash?

Succotash (from Narragansett 'sohquttahhash', "broken corn kernels") is a vegetable dish consisting primarily of sweet corn with lima beans or other shell beans. Other ingredients may be added such as onions, potatoes, turnips, tomatoes, bell peppers, corned beef, salt pork, or okra. Combining a grain with a legume provides a dish that is high in all essential amino acids.

Succotash has a long history. The dish was introduced as a stew to North American colonists in the 17th century by indigenous peoples. Composed of ingredients unknown in Europe at the time, it gradually became a standard meal in the cuisine of New England and is a traditional dish of many Thanksgiving celebrations in the region, as well as in Pennsylvania and other states.
