Green lettuce
Romaine lettuce

Due to rabbit breeding, there are many instances where dwarves are a bit bigger than expected because “dwarf rabbits” are more popular.

You can probably cut down on pellets a bit if you’re concerned about weight. At least thinking about the eggs I have in my fridge, that is a pretty solid amount. My Wick is 2lbs and he gets half an egg I’d say.
To better encourage hay diet, I would suggest less frequent veggie feedings because it sounds like you do it often (morning, night, every time you leave the house). If they’re not all bowl quantities, that’s fine, but hay is most important for a rabbit! It also helps keep your rabbit happy and healthy.
