Soft-boil the egg, about 3-5 minutes. The yolk should still be a bit runny, and the white should feel very soft when you remove it from its shell.
In a small bowl, mix the egg with the mustard and mayonnaise, until the color is mostly uniform.
Spread on toast.
Can easily be made to serve more- just add more eggs! I'd be careful about doubling the amount of mustard, however- it can easily overpower the dish. Find your personal ideal mixture.
Mr Breakfast would like to thank Anonymous Breakfast Lover for this recipe.
