Every 2 months of so, using frozen veggies, I cook up a bunch of different types, add some cooked rice or cooked pasta, mix it all together in a huge bowl, then pack it in small tupperware containers & freeze them all. I have 3 parrots, so I take 1 container out per week & feed a little to my parrots daily . I have an extra bowl I put it in when I go to work. I know someone else who freezes the same type of thing in ice cube trays & take them out & use them that way, 1 per day. My parrots don't like "chopped veggies" they prefer bigger pieces to grab with their foot & hold to eat for some reason LOL .. There will always be some kind of waste, but I just give less, or dump it out at the end of the day. Some days they eat more, others barely any. Good luck & keep us posted!
