Do you mean this one? https://produkte.migros.ch/bio-ofen-frites Hopefully it's just a delivery delay/production bottleneck. I'd really hate to see them taken out of the range too...

Maybe something for you to hope that they will be available again😄 In questions and answers it says from october 2022 they will be available again. I quote: "They are still part of our range. Due to the poor weather conditions, there were unfortunately crop failures, which is why we are currently unable to offer oven fries. We expect them to be available again from October this year and ask for your patience."
