I give my rabbits a salad every day
. They also get pellets but only about a handful or two. If we run out I don't worry too much, I just give them extra vegetables.
I mainly feed leafy green veggies and herbs such as romaine lettuce, escarole, red leaf lettuce, dandelion greens, endive, parsley, mint, basil, cilantro, carrot greens, radicchio, baby spinach, kale, bok choy, clovers, etc.
Kale and spinach are fed very sparingly, though.
They also get at least one other kind of vegetable daily and some that I feed are cucumbers, carrots, celery, alfalfa sprouts, broccoli, and brussels sprouts.
I don't feed a lot of fruit, I tend to use it more as a reward. They get a few pieces a week max. When I do feed fruit it's usually apple slices, grapes, bananas, papaya, strawberries, cranberries, blueberries, watermelon, or pineapple.
I usually buy banana chips and dried papaya slices to use as treats
Of course they have unlimited hay, too. I rotate between timothy, orchard, herb, and brome.
