VINTON — Every year, thousands of Iowa veterans request food assistance from their county veterans affairs offices, but each county handles those requests differently.Each month, a few veterans walk into Toni Parizek’s office, asking for help with groceries. She’s the director of the veterans affairs office in Benton County.“I kind of ask, kind of an estimate of how much they think they’ll need for the rest of the month to get them and their family through,” Parizek explained.She then fills out a voucher for that amount, and the recipient takes it to Fareway in Vinton.
