To address food insecurity while simultaneously reducing food waste, the best response would be to donate unused food to food banks. This approach helps ensure that surplus food is redirected to individuals and families in need, thereby alleviating food insecurity while minimizing waste.
Other strategies, such as inventorying food supplies to avoid overbuying or purchasing only what is needed, can also be effective in reducing waste but don't directly tackle the issue of food insecurity as effectively as food donations do.
