So what would be the best veggies for us to add for variety?

[Kipcha]

Right now, we currently feed,

Nearly Daily
Parsley
Cilantro

Occasionally
Romaine Lettuce
Green Leaf Lettuce (The frilly stuff)
Spinach
Carrot Tops
Kale
Grass
Dandelion

Almost Never
Banana
Strawberry
Blueberry
Carrot
Orange

Also, I have read that Nasturtiems and Pansy is good for them, does anyone have any experience feeding them the leaves from these plants?
