shredded yam & cabbage of suitably matched types can also be considered as components of the base meals.

Also – let’s look at pumpkin through this lens:

cost per lb is very low
most goes to waste
is used in many baked goods
flavor can be too idiosyncratic & strong for regular use – but flavor is apparently concentrated in the the juicy pulp, minus the seeds, which can be easily extracted and channeled separately. Making flour from best of the rest is interesting.

Following this same line of thought, while being more market innovative, similar flours/meals can be used for creating breadings & wraps in the space that spans frozen chicken nuggets to high end hors d’oeuvre wraps & potstickers.

The emphasis on the frozen end is both keto & adding more variety of what’s available for convenience & the emphasis at the high end would be just new flavor combos.
