mmmm preservatives......
I would skip the sauce and lettuce.......
Skip adding flakes and pellets also. Defeats whole purpose of making ones own food
I will try to do this myslef one day, mother permitting
My recipe would be:
Some chopped clams
some chopped silver sides
Algae sheets or nori put in food processor for a second or two.
mysis shrimp, and perhaps some fresh hatched brine
a small piece of broccolli (i hear its good for fish coloration

)
and some larger krill pieces (Like 2mm-4mm)
Put in a ice cube container (have plenty laying around)
and frozen into cubes with very small amounts of water
