For anyone who put themselves through college, this is much more a shrug than a clarion call for revolution. You can eat cheaply and well with a little effort and creativity. Good training for starting out with a young family, if any of you ever get to that point.
If you haven’t learned to cook, now is a good time. Electric pressure cooker, slow cooker, etc.. Learn to manage your time to make time for meal prep and cooking.

$100-200/yr
range without adverse health effects...maybe healthier than what you are eating now. There were times your ancestors would, and did, kill for the chance at such a diet.

Unsheltered? The problem is shelter...basic food for a year is less than three months of utilities, much less rent.
