There's only one care sheet worth reading: www.bluetongueskinks.et
I go for 50% greens/veggies, 40% meat, 10% fruit
It's not an exact science - the main point is greens/veggies should comprise most of the diet and fruit the least.
Many use low fat canned dog/cat food for the meat portion. I personally use it as a last resort and offer cooked whole meats (chicken breasts, ground turkey, shredded beef, silkworms, butterworms, waxworms, snails, etc). The important thing is variety and choosing the right foods. Check out that caresheet and that will help tons.
