Parrot Nation has a great video on making chop. I make chop for alot of birds as raise Cockatiels as well. I use a clean grain mix that has popcorn, peas, paddy rice and I add to it brown rice or other grains I pick up from a bulk store like Whole Foods. Some expamples are:
Barley (hulled not pearled)
Winter or Red Wheat
Quinua (I cook and add to the mix)
Amaranth (must be cooked and added to the mix)
Kamut
Spelt Berries
Adziki Beans
Mung Beans
Various Legumes
13 bean soup mix without the base
Chick Peas
Great Northern Beans
Black Beans
Pinto, Lima, Black Eye..
I make my grain/legume mix and let it soak overnight 10-18 hours. I drain, rinse, refill the pot and boil the mix for about 20-30 minutes. Drain, rinse and cool.
For the veggies I put everything in the food processor and chop it up:
Steamed Squash
Steamed Sweet Potato
Steamed Zuchini (raw is ok too)
Carrots
Various radishes
Brocoli or Brocoli Rabe
Greens: Kale, Dandelion, Collards such as Mustard or Turnip
Beats (greans are good too)
Frozen mixed veggies
I chop up the veggies and mix them in with the grains/legums. I add spices such as Paprika, Cheyanne, Tumeric, Garlic, Corriander...I mix it up and do different things. If you sprout, you can sprout the grain/legum mix and use that in the chop too! Keep it interesting, simple and seasonal.

You can add items like hemp and chia seed. Alpha or Kelp powder. Spirulina is a good choice as well, use sparingly and alternate supplements. I make mine in a huge 12 L resuturant style container. It lasts me 3 days! I do not freeze the veggie mix. People do, I am just not sure about how soggy the defroasted chop will be. But I do freeze the grain/legume mix for future chop batches and for bird bread.
