Mix all the ingredients, except for the crutons and let it stand for about 15 minutes. Lay them in one layer on a cookie sheet and let it roast in a 375 degrees fahrenheit oven for about 30 minutes. Let all the roasted veggies cool down. Blend these roasted vegetables in a blender to a smooth soup consistency. Use even the water that is accumulated on the cookie sheet. You can sieve this mixture if you want to or just use it the way it is.
In a saucepan, add this soup and let it simmer for about 20 minutes. Add more salt if you want to. You can add some chilli powder here if you want it a bit spicy. Garnish with croutons and serve.
