Well, not sure how well this works with just eggwhites, but honestly you will NEVER EVER hate eating eggs again.
Here is what i do:
4 whole eggs (yolk+whites)
4 pieces of whole wheat bread
beat up eggs in a big bowl, put in some pepper, and crushed cayenne pepper.
Get 4 pieces of bread, individually break up into little pieces. Break up all 4 breads into bowl of yolk.
Mix the yolk into the pieces of bread, make sure the yolk is completely soaked in the bread, or to the best of your ability.
Get a bit of olive oil for cooking in pan, and spread around pan. Dump your yolk+bread pieces into pan, and cook on low.
Make sure the bottom does not get too brown, its better if it is just touching brown.
MAKE sure to split the making into four while it is cooking, will make flipping over A LOT easier.
Flip over in pan, and cook otherside on low. BUT make sure you get your spatula and break the bread+yolk up into small pieces. I always use the end of the flipper and break it up, makes it taste really good.
Try it if your diets allows! tastes great and basic

Hopefully my instructions make sense.
