Looks delicious! I agree about the skins... just wash everything well, but no need to peel it. You could also add some yummy fresh beetroot and fresh corn, and they would be in budgie heaven
No need to peel the beetroot, and they love the leaves too
No need to take the storks off the spinach... that's their favourite part.
I used to feed my birds a delicate salad like yours once, but now they get whole vegitables, roots, leaves and all! and they love it!
