Yes, but not sure if the seeds too. Just in case I don't give my birds the seeds.
Nice work with your birds diet. A lot of people don't know how important is a varied diet for a bird. I have lovebirds and I feed them a diet of 80% pellets and 20% vegetables, fruits and seed. I searched for your type of bird specifically, because I wasn't sure they could eat the same veggies but it turns out their diet is the same. Mine really like the bell peppers and I hope yours too.
Here is a list to help you:
-Vegetables:
Corn or Sweet Corn

Spinach, chard, and bok choy should be given in limited amount as they contain high amount of oxalate.
