Poach the sausage in water, once it is cooked, slice them in half and brown in a pan. Set aside.

Cook the eggs sunny side up, make sure you don't overcook the yolks. Add a little bit of cheese onto the yolks.

Assemble on toast, first cheese, then eggs, and finally the sausage.

In a pan, heat the butter and brown your sandwich on each side, flattening it slightly with a spatula.
