Bird Bread for daily diet

[MustLoveAnimals]

I recently bought veggie bird bread, nutty cones, and donuts from The Flying Gourmet, and I'm very happy to say that my tiel and zon LOVE them.
Since they're extremely picky about everything else, could I add this to their daily diet?
Their diet consists of Roudybush Maintenance pellets, Lafeber Nutri berries, and some nuts (no peanuts), and my zon will eat dried carrots and sweet potato.
