This is a great question John! Green Salt, or powdered salicornia can be used as a salt substitute for some things. Since it's a salt water plant it can tend to have a seafood-like flavor. As far as the microplastics go, it seems to be a safe option, but I couldn't find any concrete evidence of this. Again, since it's a plant, it does contain some nutrients like potassium, magnesium, and various antioxidants, of course in small amounts since you would only be using small amounts. I have never tried it though, so I'm not sure how seafood-y it might taste.
