Preheat the oven to 180ºC fan.
First make the smoky aubergine. Line a baking sheet with baking paper or grease with olive oil. Finely slice the aubergine quarters lengthways into 2-3mm strips. Mix all the other ingredients in a bowl and season. Brush the aubergine slices with the marinade, and bake on the prepared sheet for 15 minutes. Remove from the oven, brush again with the marinade, and cook for another 15 minutes. Once cooked, leave to cool.
Make the ackee scramble. Place the vegetable oil in a medium saucepan over a medium heat, add the onion and spring onions and sauté for five minutes until softened, then add the garlic, thyme, turmeric, tomatoes and chilli, season with pepper and sauté for a further five minutes.
Sprinkle in the nutritional yeast and then add the ackee. Give this a gentle mix to coat the ackee in all the other ingredients and then allow to heat through for four to five minutes. Ackee is fragile so don’t over-mix or it will turn to mush.
Remove from the heat, add the lime juice and half a teaspoon of salt and mix in carefully. Meanwhile, toast the bagel halves and place two halves on each plate.
Add some of the ackee scramble to the bottom half of each bagel, along with a few slices of avocado and smoky aubergine, then sprinkle with pumpkin seeds, chives and coriander before adding the top half of the bagel. Serve each filled bagel with a wedge of lime for squeezing over.
