Yes, definitely hold on the veggies. Also, since Luna’s young, only introduce them slowly, as rabbit’s have sensitive stomachs and digestive tracts (you hear a lot about GI stasis and gas issues). I’d introduce one new veggie in a small amount, with a good amount of veggies you know Luna is already okay with (for Wick, romaine lettuce is his normal, and he’ll get it topped with some other things for variety).
The pace she’s consuming may be due to when you’re giving her the meals. Since it’s one presentation every 24 hours (with exception of constant hay), it’s natural she gobbles it all at once! For Wick, I give him his veggies in the morning (~6AM), then he gets his pellets (he’s never had unlimited pellets due to health issues) in the late afternoon. He’ll get a top-off of veggies before bed. The entire time, he has multiple hay access points, and he does eat the hay all day. Nothing wrong with doing one food presentation in a day though in my opinion, since hay is always there. If anything ,that does a good job encouraging hay appetite because she has to eat hay when she gets hungry later!
… And rabbits will pretty much always act like they’re starving. All the time. I actually posted in the past because I thought I was starving Wick because he was so food crazy at night, but alas, that’s normal behavior. They should eat hay, but obviously they’d prefer veggies, pellets, abd treats. Don’t give in if they’re at their daily limit! Toss the hay in some fresh hay to make it more appealing, and allow her to just eat hay in between veggie time.
