These days, a lot of people who thought they'd never need assistance, do. McBrooklyn has the information and links on how to apply for food stamps here.
And if you're fortunate enough to not worry about your next meal, consider donating cash or food to one of Sunset Park's food pantries. They're doing a great job, but they really need some support.
United Methodist (47th and 4th) provided a Thanksgiving meal to many people, and their pantry line is always very long on Thursdays. I met the pastor there last week, and he's a really great guy. Check out this link from May for more information.
