I am going to try egg whites today. Any suggestions on how to prepare them & measure them?

You cook them just like any other egg. If you are adding them to drinks or shakes make sure it is double pasteurized egg whites and not the stuff you buy at the grocery store.

Thanks we have our own chickens so I am able to use fresh eggs as needed. I bought some I cant believe its not butter spray & cook my egg white in a pan. Add a little salt & pepper its pretty good. I bought an egg poaching pain & it cooks my egg white with steam. I dont measure just use one egg white for a meal. It might be a little more then 1 ounce but I do ok with it.
