Heat oil in a large skillet over medium high heat. Add garlic and onion, cook for 1 minute, then add capsicum and cook for 2 minutes until onion is translucent.
Turn heat up to high and add mince. Cook, breaking it up as you go, until mostly browned.
Add Chili Spice Mix. Cook until mince is browned all over. (This step helps release extra flavour from the spices)
Add remaining ingredients, with 1/2 of water for Quick Cook or 3/4 of the water for Slow Cook. Bring to simmer, then adjust heat per step below:
Quick Cook - 20 to 40 minutes, uncovered, on medium low heat so it's bubbling gently; ORSlow Cook - 1.5 hours to 2 hours, covered, on low heat so it's bubbling very gently.
