I've heard of other ways but I gotta tell you these little babies are really good so maybe you could borrow one, try and and then if you like it buy a machine for $10, or off ebay (garage sales or ask around maybe someone has one they are not using and would sell you.) These are so quick and easy to make, I double and keep some in the freezer.
Things I have done with mine:
base for eggs benedict
base for egg salad,
spread with sf JAM (really good right of the wafflemaker)
spread with cream cheese and topped with salmon MMMMMMMMMMMMM!
topped with cajun seafood spread
topped with smoked fish spread
topped with PB and jelly
egg sandwich (McMuffin)
as waffles

BTW I leave out the spices so they are for more uses
I want to try adding cocoa to make ice cream sandwiches
