Preheat the oven to 200C/390F.
Prepare your red bell pepper and white onion. Get your bulb of garlic and slice off the top to reveal the tops of the cloves. Drizzle in olive oil and cover in tinned foil. Place all the veggies onto the tray and drizzle with olive oil, salt, and pepper. Place into the oven for 40 minutes, tossing the veggies halfway.
Once the veggies are soft and slightly charred, transfer them into a medium-sized saucepan. Squeeze the garlic into the pan too, careful not to burn your fingers.
Pour in your tinned tomatoes and then fill up the tin with water, swirl it around to get any leftover tomato bits and pour it into the soup. Add in your cream, followed by tomato paste, lots of pepper, and salt.
Time to get the hand blender out. You can also do this in a machine blender/food processor if you'd prefer. Blend until smooth. Then place it on medium/low heat. Once warm, taste and then season with oregano, and more salt or pepper if it needs it. Feel free to add more cream or water to adjust the consistency. You can also now optionally add in some grated gouda to the soup and give it a stir for extra cheesiness (make sure to save some for topping the baguette slices).
While you're waiting for your soup to warm up, turn on your grill and place a couple of pieces of sliced bread on a tray and cover with grated gouda. Grill for 5-10 minutes or until melted.
Give your soup another taste and season accordingly. Then divide the soup between 4 bowls. Drizzle with cream, optionally some basil, grated gouda, and your gouda grilled cheese bites.
