Preheat your oven to 400F/200C. On a roasting tray, add the squash, sweet potato, carrots, onion and garlic in a single layer. Place the thyme and rosemary on top and drizzle generously with olive oil, and season with salt and pepper. Roast the vegetables for 30-40 minutes or until softened and slightly golden.
Place all the vegetables into a blender and squeeze out the garlic. Add in the stock, milk, paprika, cumin, and blend until smooth. Adjust the level of stock and milk to get desired consistency. Season with salt and pepper to taste.
Grilled Cheese: add the cheeses between 2 slices of bread. In a pan over medium heat, melt in some butter and toast the sandwiches until golden brown on both sides. Serve with a bowl of warm soup.
