Preheat oven to 325°. Toss together the coconut, tamari, and paprika*, and bake for 10 to 15 minutes, tossing every 5 minutes. Transfer to a cool baking sheet; the “bacon” bits will crisp as they cool.
Make the dressing: Warm the oil* and add the mustard seeds. When the seeds begin to pop, carefully add the vinegar. Whisk in the maple syrup and mustard, and season with salt.
Divide and arrange spinach, squash, and red onion between 2 plates.
Drizzle dressing over spinach to wilt lightly, and sprinkle with coconut “bacon.”
