Add tomatoes, carrot, and onions to a baking tray.

Roast at 375°F (190°C) for 45 minutes until soft, caramelized, and fragrant.
Carefully squeeze roasted garlic into a blender with the veggies.
Blend until silky smooth. Let it cool slightly before blending for safety.
Season with salt and pepper to taste.
On one side of the sourdough bread, spread mustard and add cheese.

On the other side, brush with melted butter.
About 15 minutes before the veggies are done, bake the bread in the oven until golden and melty.
Close it up into a sandwich and resist eating it immediately.
Pour soup into bowls and top with pumpkin seeds, fresh basil, and a dollop of yogurt.
Dip the grilled cheese into the soup, crunch, and enjoy.
Let the roasted vegetables cool slightly before blending to avoid accidents.
For an extra smoky flavor, use smoked paprika or smoked salt in the soup.
If you don’t have Comté cheese, Gruyère or even sharp cheddar works well.
Use a high-quality sourdough bread for the best grilled cheese experience.
Can I use canned tomatoes instead of fresh?

What can I use if I don’t have a blender?
You can use an immersion blender or even a food processor to achieve a smooth consistency.
Can I make this soup ahead of time?
Yes, the soup can be made ahead and stored in the refrigerator for up to 3 days or frozen for up to 3 months.
What other cheeses work for the grilled cheese?
Gruyère, sharp cheddar, or even mozzarella can be used as substitutes for Comté cheese.
How can I make the soup creamier without yogurt?
You can add a splash of heavy cream or coconut milk for a creamy texture without yogurt.
