A hearty sandwich with a spicy grain mustard and chili sauce flavour. Perfect for picnics or brunch.
When I was on a growth spurt, my mother used to always made this for my breakfast. She didn't add mayonnaise, only chili sauce. I added grain mustard. Now, this enough for my lunch.
There's nothing to say really. You can cook the bacon in the microwave if you want. Mix the chili sauce and mustard on a small plate and spread on the bread, adjusting the amount to your liking.
