Have to ask this How do you get a reptile to eat veggies? Parrots no problem let them think its mine, that makes it automatically theirs, Reptiles??????
Started my research on them last night

Wow it looks like so much to take in. Thank goodness we didn't pick them up then and there (which we wouldn't do, until everyone has really done research)
leopard gecko is a little diffrent... since the are desert animals vegitation is rare... and there size makes it hard to "force" (like I had to do) I didnt get the larger breed either. Mine was no larger than my middle finger.. little longer if you consider the tail. Leopard geckos will eat many kinds of live prey items including crickets, mealworms, superworms, wax worms.
CRICKETS
Pros:
1. More active so more stimulating to the geckos.
2. Crickets are nutritionally superior to mealworms, containing more moisture, protein, calcium, and vitamin C than mealworms (information from Grubco).
3. Exoskeleton is thinner, so may be easier to digest.
Cons:
1 . If you buy them in bulk you need to worry about providing food and water for your crickets or they will die.
2 . Uneaten crickets will annoy your gecko, crawling on it or chewing on its toes or tail.
3 . Hungry crickets will often eat gecko feces in the cage, ingesting any parasite eggs or oocysts (stage in the life cycle of coccidia and crytosporidium that is shed in feces; basically an egg). These crickets will now carry these parasite eggs in their stomach, and when the gecko eats these crickets those eggs will hatch inside the gecko, increasing the parasite load in your gecko (see page on lizard health for more about this).
4 . The number of crickets in the cage needs to be limited for the reasons listed above. (#2 and #3), so you need to feed your geckos at least twice a week, if not more often.
5 . They stink!
6 . They get loose.
7. They chirp.
MEALWORMS
Pros:
1. They aren't very active and can't climb or jump, so no escapees.
2. If you buy them in bulk you can refrigerate them for weeks until you are ready to use them, so no worries about providing food and water.
3. They are contained in a dish until they are eaten, so they are not annoying the gecko or eating gecko poop and reinfecting the gecko with any parasite eggs.
4. Since they are not annoying your gecko you can leave a constant supply in the cage, which may allow you to only feed once a week if the food dish is large enough.
5. No chirping, yeah!
Cons:
1. You need to provide a feeding dish for the mealworms, so something else to clean and deal with.
2. The exoskeleton may be more difficult to digest.
3. Crickets are nutritionally better.
4. Mealworms will bury into the sand if they escape from the feeding dish.
5. Mealworms are less active than crickets, so less stimulating as food items.
I used to "dust" my crickets with calcium powder for a little something extra
