Introductory period (three weeks): Since children typically take several introductions of a new food to accept it, and the investigators wish to ensure a high acceptance of hummus, the investigators will spend three weeks introducing the food. The food will be provided on three days during snack time for three weeks. Prior to introducing the food, children will receive a 'lesson' involving information about vegetables using a combination of songs, rhymes and craft activities. Following the lesson, hummus and vegetables will be provided in the hummus group; vegetables only in the control group. Hummus will be provided in a pre-packaged 2 ounce serving cup; vegetables will conform to age-appropriate servings designated by the American Academy of Pediatrics (AAP) and will consist of soft vegetables (e.g., winter squash) and lightly steamed, but chilled, hard vegetables (e.g., carrots, broccoli).
