Elusive Mango Fruit

Now, just so you all know - I have a background in Food. I went to college for Restaurant Management & doubled in Hotel Technology. I had worked in a local (Northern New York) restaurant doing dishes & worked my way up to cook & assisted the owner with managerial duties before I left my hometown. Then I went to Maine for a summer - had the best Chocoate cake ever there (soaked in Grande Marne) & the best Lobster Bisque; then to Marco Island in Florida for some time & then got pulled in Jersey. The latter part of my career in Food was spent in Garde Mange - loved working with cold food - making beautiful "eye candy" platters of fruit, cheese, meat, canapes, finger sandwiches, etc. - You all know you DO really eat with your EYES not your stomach, right? *wink wink*
Well, The Blonde Frogger has been on a mango kick. He went to soccer camp for 3 weeks & the first week he was there one of the other kids had mango. It was "DEEEElicios" according to Blonde Frogger. So what is a loving mom to do, but try to please child by sending him with his favorite foods - especially fruit - for lunch during soccer camp.
HOLY MOLY!!! I have to say as a food handler...mango would not be one of my favorites!!! Not sure how to handle this fruit. NEVER EVER was it in any grocery store in NNY while I was growing up & it was not in Florida while I working there, either - (yup, probably dating myself now). So I've had to learn to deal with this fruit on my own & not very successfully, either, IMHO.
I don't know - there just seems to be a lot of waste associated with this fruit or I am just serving it wrong - not sure. First I peel the skin with a potato peeler; after that I am lost. I tried cutting it half & trying to take the core out - can someone please tell me where the heck the core IS? Then I went to the "cut the sides off & hope you don't get any "core" (?) within the slices" style. Lots of wasted fruit that way.
Now, I can cut apples, cantaloupe, honeydew, watermelon, kiwi, pineapple, strawberries (my friends look at me like I am crazy because they have never seen a mom cut fruit the way I do - well, let me tell you if they had worked for the same Chef I did in Marco, they'd all cut fruit the way I do - as he allowed no waste what so ever :-)) & have hardly any waste of fruit, but this mango is really getting to me! Arggg!!
Open for suggestions. How do you serve this fruit?

Thanks for any input...
