Nancy Zaslavsky runs culinary tours to Mexico. Cemitas is a type of sandwich from Puebla, Mexico. It's served on a rich bread sprinkled with sesame seeds. It's served with meat, avocado, cheese and the herb papalo. Papalo can be found at Coleman farms at the Santa Monica Farmers Market. Nancy likes to make her cemitas with shredded Oaxacan cheese.
