In a saucepan over a medium heat add olive oil, onion and garlic and sauté until soft and translucent.
Add spices and cook for a further two minutes until fragrant.
Increase temperature to high to brown beef mince. Make a small well in the centre and add tomato paste. Stir through mince for 2-3 minutes to caramelise.
Add in diced tomatoes. Season with the sugar, and salt if necessary. Stir through red kidney beans.
When mince comes to a boil, reduce heat to low, cover with lid and simmer for 20 minutes, stirring in between.
Meanwhile, prepare your salad ingredients.
To serve, divide mince among four shallow bowls. Arrange lettuce, cherry tomatoes, red onion, cheese, sour cream and avocado around the mince. Sprinkle with coriander and lime juice to serve.
