Start this recipe by heating the oil in a pan and soften together the onion and diced red pepper for 4 minutes. Add in the vegan mince and cook for 2 minutes before adding in the chilli spice mix. Mix together well, add in a few tbsp. water and cook down on a low heat for 5-6 minutes. Meanwhile, mix together the fresh cream and lemon juice to make a sour cream and place in the fridge. When the chilli is cooked, turn off the heat and stir in the kidney beans and chopped coriander. To serve, heat the taco shells and stuff with the chilli. Top with the diced avocado and drizzle over the sour cream.
