In a large pan, add olive oil and garlic. Sizzle on medium heat until lightly golden.
Add beef mince, lightly season with salt and pepper. Cook on high heat until brown. Add balsamic vinegar and reduce. (note 3)
Reduce heat to medium. Add lentil, stir through then add canned tomatoes, sugar, dried oregano, soy sauce, salt and pepper. Break the tomatoes apart with a spatula into small pieces. Bring up to boil then reduce to a simmer.
Taste bolognese and adjust for seasoning if necessary. Mix in half a handful of torn fresh basil. Simmer for 10 minutes, no lid.
Whilst bolognese is simmering away, cook spaghetti according to packet instructions. Remember to heavily season the water with salt.
