Start by making the cornbread. Preheat the oven to 200°C (fan 180°C). Line a deep 35 x 25cm baking tin with baking parchment. Place three-quarters of the sweetcorn in a food processor and pulse until smooth. Once smooth, mix together with the rest of the whole sweetcorn kernels.
Place all the dry ingredients in a large mixing bowl and stir well. Once mixed, add the almond milk, oil and apple cider vinegar and give everything another really good stir until well combined. Next, add the coriander, black beans, chilli, salt, pepper and sweetcorn, giving it all one final mix.
Once the mixture has come together, pour into the lined baking tin and bake in the oven for 50–55 minutes until golden and cooked through. To test if it is cooked, insert a knife into the cornbread, it should come out clean. If not, place back in the oven for five more minutes to cook through.
While the cornbread is baking, prepare the chilli. Place a large saucepan over a medium heat and add a drizzle of olive oil, the onion, celery, garlic and a pinch of salt and cook until soft, about five to 10 minutes.
Now add the chilli, rosemary, thyme and tomato puree and cook for another five minutes. Add the beans, tomatoes, 150ml water, maple syrup and some pepper and bring to the boil, then lower the heat and leave to simmer for 25–30 minutes, at which point it should have a thick consistency.
When you are ready to serve, sprinkle the chillies and spring onion over the top and enjoy with the cornbread.
