Frozen Food is often served to birds as a favourite food. It is easy to serve up, lasts longer than fresh fruit & veg & something you don't really have to clean, cut or prepare in any way. Most bought frozen veggies do contain sodium in the ingredients so read the packs before you buy them. As an alternative you cut large batches of fruit & veg up, blanch them in boiling water for a few minutes & then freezes them.
Dried food is another popular easy food to offer to your parrots. Most of the bought dried fruits contain sulfur dioxide. For under $100 you can pick yourself up a cheap dehydrator, slice the fruit & veg up, dry it & bag it into zip lock bags.
