Cold potato is a great lunch box addition for supporting gut health. It is a good source of resistant starch, which is food for our healthy gut bacteria. This quiche uses thinly sliced potato in place of pastry and works equally well with dairy-free milks.
Dairy-Free: Parmesan cheese is one of the least allergenic dairy foods, due to the aging processes, which helps to partially digest the proteins. However, for a dairy-free version, just omit the cheese.
