It's just gone 3:00 pm at the Lichtenberg youth centre in east Berlin, where youngsters are laying out cherry tomatoes and carefully chopped cucumber as they get ready to prepare dinner together.
For many of them, the weekday ritual is an eagerly awaited moment.
"We notice it a lot especially among the teenagers, they ask us: 'When can we eat? I haven't eaten all day'," said Patric Tavanti, head of the centre run by the charity Caritas.
Many of the youngsters' parents often lack the money or the time to provide regular meals, he said, adding that the centre aims to give the youths a space "where they can feel at home".
"I come almost every day," Leila, one of the teens, told AFP. "We chat, cook together and just have fun."
In Europe's powerhouse, the economy is humming, public coffers have never been fuller and unemployment is at its lowest since reunification in 1990.
Yet some 20 percent of under-18s live in "relative poverty", according to the family ministry, defined as living in households that have to get by on less than 60 percent of the average German household income.
For a single parent with one child, that amounts to a monthly net income below €1,192 ($1,470).
For a family with four children, it's under €2,355.
Despite record employment, only a third of the parents of Germany's roughly 2.8 million impoverished children have jobs, said Heinz Hilgers, of the Child Protection Association (Kinderschutzbund).
Beyond the material shortcomings they suffer, growing up poor takes its toll in many other, more insidious ways.
"It's a downward spiral," said professor Klaus Hurrelmann, of the Hertie School of Governance in Berlin.
"The children feel excluded, they start to feel ashamed when they can't join in school excursions or invite friends over for a birthday party. They end up losing confidence in themselves and struggle at school," he said.
Falling behind at school
Tavanti, of the Berlin youth centre, said it was a phenomenon he had witnessed first-hand.
"Just one of our adolescents is currently trying to pass the Abitur," he said, referring to the secondary-school leaving certificate required to pursue higher education.
He believes many German schools struggle to meet the needs of these at-risk children, who often come from immigrant families or single-parent homes.
"We're seeing a growing need for food, but also for help with homework and reading," agreed Lars Dittebrand, who runs the Manna family centre in Berlin's Gropiusstadt area, famed for its towering social housing estates.
Compounding the problem is Germany's early-age education sorting system, critics say, which can prematurely put disadvantaged pupils on a less academic route, potentially leading to lower-paying and less secure jobs.

Decrying what it calls "hereditary poverty" in Germany, a study by the Bertelsmann Foundation think tank found that just some three to 16 percent of households, depending on calculations, managed to cross the poverty line and improve their lot.
"That's how generations of poor children become poor adults and poor parents," said Hilgers, of the Child Protection Association.
As well as being a stain on Germany's conscience, it's "a huge economic risk", he warned, in a greying nation already grappling with a shortage of skilled labour.
'Making their own way'
Germany's new government, a repeat coalition of Merkel's conservatives and the centre-left Social Democrats, has vowed to tackle the challenges by raising child benefits, offering more child care facilities and all-day schools to make it easier for parents, especially mothers, to work.
But for lawmaker Lisa Paus, of the opposition Greens party, those promises don't go far enough.
She said Germany urgently needed to do more to support single parents.
"Poverty often starts when couples split up," she said.
Indeed, statistics show that 45 percent of children raised by a sole parent, usually their mother, live in relative poverty.
Some politicians and campaigners have called for a basic monthly income for children of around €500 for the lowest-earning households to help break the poverty doom loop.
But for a government determined to maintain a balanced budget, any hint of lavish spending is anathema.
Instead, Family Minister Franziska Giffey plans to introduce a law in coming months aimed at improving the quality of daycare facilities, with a bigger emphasis on early-child development.
"Every child should be allowed to make their own way, regardless of where they come from and where they grew up," she said.
