Preheat the oven to 350 Fahrenheit (175 Celcius) and grease a large size muffin tin.
In a large bowl, combine everything except the eggs, cheese and chives. Mix well using your hands.
Using hands soaked in water to prevent sticking, separate the pork mixture into 12 equal portions and press into each muffin cavity, pressing up and over the sides.
Pop the pork muffin tin into the preheated oven for 10 minutes.
Meanwhile crack an egg, and separate the yolk from the white. Leave the egg yolk in the shell, and add the egg white to a measuring jug.
Remove the pork cup from the oven after 10 minutes.
Add one yolk into each partially cooked pork cup.
Using the measuring jug, add some egg white into each cup, making sure not to overflow. (Note: you do not have to use all of the egg white)
Add enough cheese to cover the top of each sausage and egg cup.
Bake for another 10 minutes (increase this to 15 minutes if you do not want a runny egg yolk).
After 10 minutes, turn off the oven, but leave the pork and sausage egg cup in the oven for another 5 minutes.
After 5 minutes of resting, remove from the oven.
Top with chives and serve.
