A teenage boy at the Mascoma Valley Regional High School in Cannan, New Hampshire, did not have any money, so Ms Kimball said he could have his lunch anyway and pay for it when he was able.
His parents sent him to school with the cash, the equivalent of €7.16, the very next day, but Ms Kimball was sacked by the franchise offering school lunches, Café Services, for her decision, which the firm qualified as 'theft'.
Andrés, 49, who is from Asturias but has lived and worked in the USA for well over 20 years, tweeted: “If [Bonnie Kimball] needs a job we have openings at The Think Food Group. If you know her, let her know!”
The Think Food Group is a chain Andrés is about to open, adding to his existing restaurants in Washington DC, Los Angeles, Miami, Las Vegas, San Francisco, México DF and the island of Puerto Rico, where he dished out free food to help the victims of Hurricane María.
Bonnie Kimball's case reached the State media soon after she was fired in March and has recently hit the world's headlines.
As a result of the media repercussion, Café Services offered her her job back, but she refused, because she believed this move was only designed to keep the school sweet so it would renew their franchise.
Several of Ms Kimball's colleagues have since resigned in protest over her being sacked.
In a country blighted by extremes of rich and poor, hundreds of thousands of pupils are unable to pay for school lunches, meaning they are forced to go hungry all day.
Although José Andrés is a top chef, he works closely with the grass roots and is committed to humanitarian aid.
Recently, during president Donald Trump's shutdown, Andrés served free food in Washington DC to public sector workers who had not been paid for up to three months.
