Spray a large frying pan with low calorie cooking spray and add the onion and pepper. After frying for around 4 minutes, and once the onions and peppers have softened, add the garlic and beef mince. Fry together for another 4 minutes until the mince is browned on all sides.
Add to the bottom of the slow cooker and pour in the chopped tomatoes, kidney beans, tomato puree, Worcestershire sauce, chilli powder, cumin and Sriracha sauce.
Give the slow cooker a good stir, crumble in the stock cube and cook on medium for 3 hours.
Preheat the oven to 190ºC. Spray 6 small bowls with low calorie cooking spray and set them on a baking tray. Use 2 baking trays if you need to.
Microwave the tortilla wraps for 30 seconds to make them a little more workable. Place each wrap inside a small ovenproof bowl, pressing firmly into the edges. Pop the bowls into the oven for 4 minutes until lightly golden. Remove from the bowls and leave on a wire rack to cool.
While the chilli is cooking, add the rice to a pan of water and cook according to the packet instructions.
When the rice and chilli are cooked, you are ready to assemble your bowls. Spoon the chilli into the bottom of each tortilla bowl and add a spoonful of rice. Finish each bowl by topping with a sprinkling of cheese and enjoy!
