Heat a little oil in a large frying pan or skillet on a medium high heat. Dice onion and cook, stirring until the onion is soft but not super browned.

Add meat and salt and cook for 3-5 minutes, stirring to break up the chunks, until the meat is no longer pink.

Add the lemon juice and cream. Cook for another few minutes for the sauce to reduce a little.

Taste and season with more salt or lemon as needed (trust your judgement)

Serve on a bed of baby spinach with parmesan shaved over.
