The phrase suggests an abundance of a specific type of food, often implying a quantity sufficient to satisfy a large group or a particularly strong craving. For example, ordering several pies for a party ensures that guests have enough to eat and a variety of options from which to choose.
Having a surplus of readily available sustenance offers convenience and can reduce stress related to meal preparation or unexpected needs. Historically, celebrations and gatherings have often featured copious amounts of food, symbolizing prosperity and hospitality. Ensuring there is an adequate supply for all attendees fosters a sense of generosity and well-being.
