Some time ago, I entered the almost calorie-free and gluten-free "Shirataki noodles" in the product ideas for quick meals and a lot of migipedialists expressed interest in it:

For your information: Coop now offers shirataki noodles http://www.coop.ch/pb/site/retail/node/71140745/Lde/index.html?wt.mc_id=1_CP_NL,2_KW2015-19,3_active&mtype=nl

There are also the super noodle reform stores and online stores, often in organic quality, precooked or dry.

Migros could even top Coop if it offered Shirtaki in organic quality and/or from European cultivation :-).
