Food waste is a global issue; around 1.3 billion tonnes of food waste is generated annually, with Pakistan producing 36 million tonnes of food waste. Consequently, restaurants are the leading source of food waste. However, identifying the causes and dangers of food waste in the restaurant's process flow is crucial. As a result, a restaurant framework is necessary for process flow rectification and identification of critical control points. The current research, which employed a qualitative approach, establishes a framework that outlines the critical controls and their impact on social, environmental, and economic issues. The data was gathered through structured interviews and observations from multiple eateries. The framework includes redesigning flexible menus, offering employee training, reducing plate sizes, implementing a forecasting system, and implementing a lean inventory management system to effectively reduce food waste. The paper presents policy suggestions to food regulatory agencies and restaurants based on its research and approach
