Use a 2 1/2 to 3 inch heart shaped or round cookie cutter to cut out a hole in both slices of bread.

Heat a medium size frying pan over medium heat and melt half the butter.

Put one slice of bread and one heart into the pan. Divide half the cheese between the slice and the the heart and do the same with the cooked chorizo and top with the rest of the cheese. Top with the other slice of bread and heart.

Use a spatula to press the slices of bread and hearts together until the bottom has become golden brown. Add the rest of the butter to the pan and flip the sandwiches.

Crack the egg into the heart shaped cut out making sure there's enough butter in the pan (if not, add a bit more).

Cover the pan with a lid to cook the egg until the white are set and the yolk is still runny (if you like a harder yolk, flip after 2 minutes and cook 2 minutes longer).

Serve together and use the heart to dip into the yolk. Enjoy!
