Hi lisa!
Well I'll tell you why I don't use real eggs I don't know if anyone else agrees or what but I use them because they are lower fat, and lower calorie and they last longer than real eggs which is a bonus cuz i don't eat a ton of eggs. You can find them in your grocers dairy case where they keep the eggs usually the substitutes will be on the top shelf and in cartons
As to the ranch, I don't buy premade ranch dressing, I buy fat free sour cream and a packet of hidden valley ranch flavoring and you end up with only 25 calories per serving and 0 fat I don't know what Krafts pre-bottled contains but I like the way I make it just the same.
I hope this helps!
Good Luck
Michelle
