I'd need to think on that one for a bit. It wouldn't be easy, but it's do-able. Questions would be how much they're willing to cook, and how old are their kids....
I could get by on $2600/month, but it would be hard. Short-term, we'd be OK. Long-term, we'd need to make some lifestyle changes. And really long-term, we'd not retire, ever.
The kids do get the free school breakfast/lunches so that should be added as a non-SNAP food benefit.
