I’ve never tried this.......but an individual who juices whole vegetables for health drinks said she took the leftover pulp, spread it out on a sheetpan, and dried it.
Said the dried veg pulp was a nice addition to recipes.
Could do this w/ pulp leftover from juicing tomatoes, carrots, beets......and so on.
My first thought was adding it to meatloaf.
