I used nine whole eggs instead of the whole egg/egg white mix, and used a 10" skillet instead of a 12" skillet because the pie plate I usually use to store it is 10". The frittata is "higher", and needs a bit more cooking time, but I like it better. I think it needs one extra egg, for texture, but that'll still fit comfortably in the 10" skillet. Tasty as fuck.
