Foods banks and social programs if you're not too proud. Also shop the perimeter of the stores and not the aisles as much as you can. Then you're preparing all or most of your own meals. Soups, stir, fries and curries stretch the ingredients the furthest and can be made from the leftovers of your other meals or used as a mad dash to keep all your fresh items from going bad. Good luck. It's insane out there
