Hi again, do the monitor a favour; stop feeding turkey mix, ONLY whole prey.
Rodents, birds (chicks), fish (fresh or saltwater), prawns, shrimp, crab claws (break a large claw), though my Ornate could even break a 6 to 8 inch claw with a couple of crunches!
They love snails too, make sure no pesticides have been used. The freshwater type are fine, you can usually get them in aquarists shops..
