Heat the spray oil in a large frying pan over a medium-high heat. Add the beef mince and cook, breaking it up with a wooden spoon, for 4-5 minutes or until brown and cooked through. Add the paprika, cumin, ground coriander, garlic and stir through for 1 minute or until fragrant. Add the tomato paste and 80ml of water and stir for 1-2 minutes until well combined. Set aside.
Make the quick guacamole, mash the avocado with a fork in a bowl. Add the yoghurt, lime juice and chopped coriander and stir until combined.
