Potatoes and carrots clean and cut into not too fine. Put to cook for about 10-15 minutes. Then poured out of the pan half of the water, the rest decanted into any other container.

(Step for beauty and fragrance, but optional) At this time, finely chop onion and begin to fry it. Fry have to much gold color - brown

So, you have in the pot boiled carrots and potatoes. Preventing them in a blender until smooth. Then cut small cubes not melted cheese and throw in the resulting mass. Interfere with blender, pereodicheski to taste by adding water from the vegetables (OR strong desire a washed-up chicken broth). Why optional? I personally like thick cream soup, and someone who likes watery. See for yourself. Salt. Don't forget to add salt, because even crackers is salt, but if you don't salt the soup (because we weren't salted boiling vegetables) it will be very bland.

Then add the croutons and onions and enjoy your lunch! Bon appetit :)
