40 g plus whatever you'd like to use when it's done.
#9 sized aluminum cups (if you have them)
From the bread flour all the way down to the dry yeast on the ingredients list, combine them all in a bread machine, set it to the dough making setting, and let it do the first rising.
Once the dough is done, transfer the dough to a flour coated working space and punch the dough. Make it into one ball and let it sit for 15 minutes.
Shaping the dough. With a rolling pin, roll out the dough to a 25cm high by 34cm wide shape. (It's okay as long as it's close.)
Cut the dough in half and then take the sliced 1cm strips of ham, thinly sliced onion, and cheese and place it on top. The top 2 cm are going to be the lip, so try to avoid covering that area.
From the bottom to the top, roll the dough up and make sure to close the dough properly. Divide into 8 parts and put them in the aluminum cups. Arrange them on a baking sheet and let the dough rise a second time till they are about 2-5 times bigger.
Once it's done, coat the tops with the beat egg and top with any more cheese that you may desire. Finally top with mayo in a circular motion.
Preheat your oven to 200°C and then bake them for 12-13 minutes.

Story Behind this Recipe
I make toast a lot so I thought about combining the idea and making a roll.
In Step 5, if you have too many toppings, the rolling might come undone, but if it more or less stays the same, you should be fine. If the toppings come out the side, just put them back in the center of the dough and roll it up gently and you should be fine. You can also use pizza cheese instead of mozzarella, and bacon for the ham.
