Start by cutting the squash into quarters, remove the seeds and stringy middle. Add oil, thyme, chopped garlic, salt and pepper and roast for about 45 minutes at 180C Once the squash has finished roasting, scoop out the middle (discard the skin) and add it to a food processor with a little more olive oil, and a pinch of sea salt. Slice the mushrooms and sauté them with the garlic, salt and pepper, squeezing the lemon onto them once they’re golden and have finished cooking Spread the pumpkin puree onto a thick piece of toast, then add the mushrooms and sprinkle the fresh tarragon, pumpkin seeds and almonds on the top.
