Preheat the oven to 180°C fan/200°C/gas mark 6.
Cook the quinoa according to the packet instructions, adding the stock to the water for flavor.
Chop the sweet potatoes into 1–2cm (½–¾in) irregular chunks (no need to peel if organic, just give them a good wash), then add to a baking tray with a drizzle of olive oil and salt. Roast for about 20 minutes, or until lightly browned.
To a small, high-powered bullet blender, add all the tofu cheese ingredients and pulse to combine. Season to taste. It will be thick – it’s intentional!
Shred the red cabbage into a small bowl with a potato peeler, then add half the lime juice, a pinch of salt and pinch together with your fingers until it turns a pinky- purply shade. Set aside in the fridge.
Heat a dry non-stick frying pan on a medium-high heat and add the sweetcorn. Fry with a pinch of salt, for around 10–12 minutes until lightly charred, then take off the heat and set aside.
Now for the sweet potato marinade. In a small bowl, whisk the 2 tablespoons of olive oil, the remaining lime juice, the red chili, a pinch of salt and agave syrup together. Pour over the roasted sweet potato and carefully toss to cover.
Time to assemble the jars: put the cooked quinoa in first, then the black beans, sweet potato, tofu cheese, red pepper, kale, red cabbage, charred corn, coriander and pumpkin seeds.
