Take a large pan or wok. On medium heat, add the oil and garlic and fry for a few seconds until it gets some colour
Turn the heat down to low, add the onion and gently fry for 5 mins until they’re really soft. Keep moving them around so they don’t burn.I like to put the lid on the pan because the steam helps to soften the onions as much as possible
Turn the heat up to medium, add the carrot and continue frying for 2mins
Add the mushroom and fry for about 3 mins or until the mushrooms start to soften
Push the vegetables to the edges of the pan, leaving a space in the middle, add half the beef mince and fry until it starts to brown. Push the meat to the edge and add the remaining mince.(If you add all the mince at once, the temp of the pan goes down suddenly and your mince won't be as juicy).
Once the meat has almost completely browned, add the frozen peas and mix everything together
Turn the heat to low, add the passata, mixed herbs and smoked paprika. Mix well, breaking up any clumps of beef
Simmer for 5-10mins with the lid on (ensure there's a gap for steam to escape) and you're done!
