To make a ultimate veggie chilli recipe, you'll need: 1 tbsp paprika, 1 chopped onion, 2 chopped garlic cloves, 1/2 cup tomato paste, 1/4 cup chopped coriander, and 1 cup water. Bring to the boil over medium-high heat. Reduce the heat to low and simmer until the onions are soft, about 30 minutes. Add the tomatoes and cook, stirring occasionally, until they're reduced by half. Remove from heat and stir in the remaining ingredients. Serve with sour cream, if desired.
