That’s a great list that Moxie gave you.
You can keep her on baby pellets until she’s approx. 6 months, then switch her to adult pellets. We recommend a small amount of pellets be fed every day since that way you know your bunny is getting the nutrients she needs. If you want to go all hay and veg, it puts rather a heavy work-load (and economic pressure depending on where you live) on you, because you’ll need to supply a vast variety of different greens every day. It just feels safer to feed some pellets.
That said, the mainstay of a healthy bunny diet is hay. Good quality hay has most of what a bunny needs and the fiber is so important to a bunny that it can barely be overstated. 80% of her diet should be hay (you can’t compare directly when you add the weight of daily pellets, hay and vegs since vegs are like 80-90% water and a bunny never should finish all its hay, so you’ll have to make an estimate).
Good starter vegs would be romaine lettuce. Dandelion. Piece of kale. Mint sprig. As Moxie says, go very slow. Suitable treats are slice of apple, tiny slice of banana, half a grape. But not every day, it’s like kids shouldn’t eat candy every day.
