Use this same idea to replace all bread to make sandwiches, pizza and even garlic cheese bread!
Separate eggs. Whites in one bowl, yolks in another.
Add cream cheese to yolks and mix until smooth. In the other bowl add cream of tartar to whites, and beat with hand mixer on high until fluffy and peaks form.
Carefully add the yolk mixture to the white mixture and fold to combine.
Let cool on a wire rack. Once cooled, store in ziploc bags or tupperware overnight. Like Magic they turn into "buns".
