Pronunciation: [CHIH-lee (Sp. CHEE-lay) kon KAY-soh]
Spanish for "chiles with cheese," this warm melted cheese dip is flavored with chiles (typically jalapeños) and more often than not chopped tomatoes, onion and garlic. The cheese base is usually cheddar or jack, though Tex-Mex versions traditionally use Velveeta, a processed cheese (see cheese). The classic accompaniment for this dip is tortilla chips.
