Most of today's Mexican food is based on ancient traditions, such as the Aztecs and Maya, combined with culinary trends introduced by Spanish colonists. Quesadillas, for example, are a flour or corn tortilla with cheese, beef, chicken, pork, and so on. The indigenous part of this and many other traditional foods is the chili pepper. Foods like these tend to be very colorful because of the rich variety of vegetables (among them are the chili peppers, green peppers, chilies, broccoli, cauliflower, and radishes) and meats. The French occupation of Mexico influenced Mexican cuisine with baked goods such as sweet breads and the bolillo, a Mexican take on the French roll. There is also a minor Asian influence.
