To prepare the roasted vegetable puree soup, prepare the vegetables for roasting. Cut the pumpkin into pieces, remove the seeds and pulp (you can leave the skin on). Cut off the top of the garlic bulb (no need to peel it) to make it easier to take out the cooked cloves later. Peel the onion and carrot, cut the bell pepper into quarters and remove the seeds, and simply rinse the cherry tomatoes. Take a baking sheet, line it with parchment paper and arrange the vegetables on top. Season with salt to taste, add dried herbs de Provence, and drizzle with a small amount of olive oil. Roast in a preheated oven at 180°C (350°F) for 1 hour.
