I have tegus and a blackthroat monitor.
The tegus eat mice, baby quail, small rats, a small amount of ground turkey, eggs, and fruit(they seem to like the granny smith apples and grapes best, but get quite a variety).

The blackthroat eats mice, baby chicks, small to medium rats, some ground turkey on occasion, eggs, and on occasion fish.

The fish I get locally. Technically it's bait fish, makerel mainly. But it's caught and packaged locally and is fresh and whole and good. I've actually cooked some right out of the same package for the lizards.

The MAIN diet is mice for all the lizards(with a LOT of fruit for the tegus). The rest is off and on, with ground turkey almost exclusively for when I happen to run out of rodents due to poor planning, OR if I was dumb enough to not thaw rodents and it's too late to do so. (Or in one case when the silly cat got the thawed mice.. sigh. Pets...)
All rodents are frozen/thawed for my lizards. I don't like to feed the lizards live rodents.
Hope this helped.
