You can give a veiled greens (dandelion, kale, collards, curly endive, escarole, mustard greens, etc.) and veggies (carrot, squash, zucchini, sweet potato, sweet red pepper, etc.) and a bit of fruit (apple, pear, berries, melon, etc.) The leafy things can be hung in the cage. Slices of things like apple, pear, red pepper can be impaled on the branches or things can be chopped up and put into a dish. Whatever the chameleon doesn't eat will feed any crickets that you might have in there.
