What kind of chameleon? The only one that will eat fruits or vegetables are Veilds. I have seen a few Panthers on here eat some fruit, but that is not the norm. I have seen people feed their Veilds strawberries and Kale. Not sure of what else they like. They will also eat the plants the enclosures, so make sure the plants you use are not toxic. Some will eat Hibsiscus flowers which are safe.
