How can I persuade my parrot to eat veggies?

I have a 3 year old DYH amazon, she doesn't really like veggies either. She does enjoy banana peppers...also, the vitamin A in peppers that they need can also be found in sweet potatoes. My 'zon LOVES baked sweet potato. Since he mostly likes sweets, just be on the lookout for signs of diabetes, which 'zons are prone to having.
