What country are you in & what species are you feeding?
There's plenty of good food available in the UK but it can be harder to find in the US.

There are lots of veg they can have, too many to list really but favourites are things like broccoli, cabbage, kale, cauliflower, romaine lettuce, sugar snap peas or mange tout, bell peppers, carrots, pumpkin or butternut squash, potato or sweet potato must be cooked but are often enjoyed & cucumber to name a few, nothing from the onion family & no garlic, no iceberg lettuce.
Always begin feeding veg in very small amounts & experiment with different things to see what your ham enjoys.
