Cooked pasta = yes preferably no sauce.
Raspberries and blackberries = well i have never seen anything that says they are toxic to them. I don't think they have much nutritionnal value. As a general rule, the more orange or deep green a veggie is, the richer in nutriens (this is a crude generalistic rule though). I give mine rapsberries or strawberries from time to time, so i can get a kick out of the mess he makes.
Great fresh foods are brocoli, peas, carrots, green beans, and some lettuce. Not iceberg though that's just useless.
The big NO-es are avocado, rubarb and chocolate. These are toxic to most birds.
Also don't give them too much onions (particularly raw) or tomatoes. Mushrooms i heard aren't great either.
