Definitely carrots, Napoleon LOVES them! Also try some romaine lettuce.
What I hear over and over is that variety is the most important thing. I go to the grocery store a few times a week and graze the salad bar for Napoleon. I end up spending like 20 cents each time, and it lets me buy just what I need of lots of different things.
I found this list posted on Yahoo Answers (apparently sourced from
http://www.turtlepuddle.org/health/turtlefood.html) and printed it out for reference:

Reptile Tri-Cal or Rep-Cal are the best calcium/D3 supplements by far. A jar of Rep-Cal is rather expensive, but lasts a very long time. Tri-Cal even comes in a handy shaker bottle. Use once a week. Vitamin supplements may also be used.
(Don't use any supplement that has phosphorous in it.)
