Here is a bit of info from our RTB Caresheets.
FEEDING AND WATERING
The green iguana is strictly veggies and fruits. This may sound more simple opposed to feeding most other insectivorous lizards, but on the contrary. It is actually not as easy as it seems. Iguanas must be fed a wide variety of leafy greens, bulk veggies, and fruits. Leafy greens include things such as kale, collard greens, bok choy, endive, spinach, watercress, escarole, and many others. Most types of lettuce and cabbage are not good for them and contain very low nutritional value. Bulk veggies include, summer squash, carrots, and some others that are not usually found in stores (I am naming only examples that are usually easy to find.) Fruits include kiwi, bananas, grapes, strawberries, and pineapple are good examples of fruits. As far as the portions go, about 2/5 of the bowl should contain leafy greens, another 2/5 of shredded up bulk veggies, and 1/5 fruits. I also like to sprinkle "Iguana Diet"™ on the food for added nutrition. Make sure that all your food that you feed your iguana is pre-washed and free of chemicals. Also, iguanas should be fed about once a day, everyday.
The lettuce is ok but provides little nutrients. Add greens to your list when fixing it's food.
