Heat 4 Tbsp. of the oil in a large saute pan or pot over medium-high heat. Add onions and cook until translucent, 3 to 5 min. Add carrots and celery; season lightly with salt and pepper and cook for 2 more min., stirring occasionally. Add tempeh, Cuban Island Spice, and 1/2 cup water and cook for 2 to 3 min., crumbling the tempeh as you stir. Reduce heat to medium-low and stir in almond milk and nutmeg. (Rub whole nutmeg against the surface of a small grater to grate.) Cook for 3 to 4 min. then increase heat to medium and stir in wine. Cook until most of the wine has evaporated, 10 to 12 min. Reduce heat to medium-low and stir in tomatoes. Cook, uncovered, for at least 10 min. or up to 1 hour depending on how thick you want the sauce; stir occasionally.
Meanwhile, make zoodles using one of these methods: Use a vegetable peeler to shave zucchini lengthwise into thin ribbons then slice the ribbons in half lengthwise. Or slice zucchini into 4-inch long thin matchstick-like strips. Once the bolognese is done, heat remaining oil in a separate large saute pan over medium heat. Add zoodles, season with salt and pepper to taste, and cook, stirring, for 2 to 3 min. Transfer to plates or bowls and top with a generous portion of bolognese.
