Mine get all the timothy hay they can shove into their mouths; a few (<1/2 of a tbs) Oxbow Science pellets (usually in a puzzle feeder type toy); fresh veggies every night (bunny safe, varied); and a few fruits/treats for training purposes.
But these are adult rabbits, so their nutrition is a little different.
I see the argument between Sherwood and Oxbow- so I'll throw in my two cents. The Oxbow Science has timothy hay as the first ingredient (big plus for me) and then high fiber content, low protein content. To be fair- a small disclaimer, I get oxbow products at a discount right now, so there is that bias.
