Heat the oven to 170°Place the slices of butternut squash in a dish with a tablespoon of the oil and a good sprinkling of salt and pepper. Bake in the oven for 30-40 minutes until soft and caramelised around the edges.
Just before the squash is finished cooking place the herbs, remaining oil, garlic clove and lemon zest in a pestle and mortar or mini blender and blend together.
When you take the squash out the oven top with the herby gremolata and the flaked almonds and serve.
