I hope that I am not offending you but some people might be looking for an actual answer, and comments like these are bumping those answers down to the the bottom. ( I am not trying to offend you, sorry if I did)
But he is right. You want a feeder that is a good staple and easy to breed that isnt a roach or cricket, well the sad fact is that doesn't exist.
If we make a list of wants that includes.
Staple nutrition,
Low chitin (again for a staple),
Easily gutloaded,
Easy to breed, requires little time,
We have 2, Crickets and Roaches. That is the end of the list, everything else does not meet some of those requirements.
Take the other common foods,
Silkworms - Staple Nutrition, Soft Bodied, Not gutloadable, Not easy to breed.
Superworms - Easy to breed, Gutloadable, High in fat and chitin, not a good staple.
Isopods - Easy to breed, Gutloadable, Extremely High in chitin, also in calcium, too hard to digest to be a staple.
Hornworms - Good Nutrition and Hydration (maybe not staple), Soft bodied, Extremely hard to breed.
Locust /Grasshopper - Staple Nutrition, Low Chitin, Hard to breed.
Stick Insect - Good Nutrition, Gut loadable, Easy to breed, Illegal in the US. Hard to find food for, for some
Flys - Staple Nutrition, Soft Bodied, Easy to breed with caveats, Lots of maintenance high escape rate.
Katydid - See stick Insects.
Part of owning a chameleon is dealing with roaches or crickets or both. One of them is going to have to be fed, period. If you cant deal with Live Roaches or Crickets, then you need to look at other animals.
We go over this about 25 times a week. People wanting to feed just worms ect. Can we just get a big banner on the site, that if you are not prepared to deal with roaches or crickets look at a different pet!
Before someone jumps in and says "You can do fine without roaches and crickets". I will agree and experienced keeper could, however balancing hard and soft everyday and making sure they get enough of both and not too much of 1 is very difficult and takes knowing cues from your chameleon. You will be walking a fine line of Impaction and diarrhea. While also greatly limiting the variety that chameleons need.
