Reheat briefly and garnish with mayonnaise and onions if necessary.
From Friday there is a special weekend deal at Aldi, namely a frikandellenvlaai for only € 3.99. Last year the frikandellenvlaai started as a joke at Bakkerij Engels from Grubbenvorst. The joke was a huge success. People were queuing for the frikandellenvlaai. Secretly curious? Friday, Aldi… You know where to go.
Or get started yourself. For example with this recipe for a frikandel flan.
