Bollo is kind of like a biscuit or a cookie that people in Ecuador like to eat. It's made from a type of corn flour called masa, and it's usually cooked over an open flame until it's nice and crispy on the outside. Some people like to eat it with cheese or avocado, or even spread some peanut butter on top! Think of it like a yummy snack that you might eat after school, but instead of chips or crackers, it's made of corn and cooked in a special way.
