What is th what is the meaning of the breadbasket colonies

The "breadbasket colonies" were also called the "Middle Colonies," and they included Pennsylvania, Delaware, New York and New Jersey. They grew far more food than the Southern or New England colonies, and each farmer had his own farm of between 50 to 150 acres

 The Middle colonies were not known for their farming as well as they were known for their mills and bread. On average in the Middle colonies, people ate about 1 pound of bread per day.

The main foods you got out of these grains were pancakes, waffles, and pretzels.
