Cut the squash into 1” slices, remove and discard the seeds, then cut each slice into half-moons. Toss in the olive oil, then sprinkle on the paprika, cumin, salt and pepper. Place in a single layer on a baking sheet and cook in the oven for 20-25 minutes, turning once halfway through cooking.
Whilst the squash is cooking, make the dressing by mixing together all of the dressing ingredients using a fork. Pour into a small serving bowl.
Take the squash out of the oven and put to one side. Divide the spinach between three plates. Top with slices of squash, then sprinkle with goats cheese, pomegranate seeds and pine nuts. Serve with the pomegranate dressing.
