2 egg whites
1 T nonfat dry milk
yellow foodcoloring, optional
Sprinkle milk over egg whites and then beat until smooth. Use in place of 1 egg. May be somewhat dry and so consider cooking with other oils/fats.
I do know Holly makes egg substitute by doing like 12 egg whites & 1 egg yolk to get some of that needed fat in there. The best part of this recipe is the significant cholesterol reduction and the significantly reduced price (over buying Egg Beaters).
