In a bowl, mix together the pancake mix and milk to make the dough.
Pour the dough into an aluminum foil pan.
In a separate bowl, mix together the mayonnaise, mentsuyu, salt, and pepper. Pour this mixture on top of the dough.
Lastly, top with mayonnaise, then toast for 10 minutes. While toasting, if the top surface seems like it will burn, lay some aluminum foil on top.
Once done toasting, finish up by adding parsley to taste.
Notes
I tried making the bread easier by using the pancake mix. It’s quick and simple to make so it’s a great breakfast or snack option. The top burns easily when toasting, so be sure to cover it with aluminum foil part way through.
