Prick the sweet potatoes all over then microwave on high until tender - around 15-20 minutes
Smash potatoes between two sheets of baking paper with a burger press, spatula or pan
Heat a non-stick frying pan over a medium high heat
Add the cheese to pan in small rounds, roughly the same size as the smashed potato
Top with the sweet potato, cook until golden and crispy then flip and cook until golden and crispy on the other side
Cook a few at a time if you have space
Wipe the pan clean
Heat the chilli oil over a medium heat, crack the eggs in and cook to your liking
Put a lid on or a bowl over for about 15-20 seconds towards the end to cook the egg white
Stack the sweet potatoes, top with the egg, creme fraiche, pickled onions, chilli crisp and chives or spring onion
