Ornate Horned Frog's diet?

i have a Ornate horned frog. i have been seeing a bunch of vids on youtube.com of people that feed there frogs mealworms, anoles, fire belly toads, and in one case a finch. when i got my frog he was amout the size of a nickle, and i fed him crickets. now hes about 2 - 2 1/2 inches across, and i feed him crickets and the occasional pinky. Is it ok to feed the other stuff to him?
