Boil the vegetables and when they are ready drain the water from the pot but keep 1 glass of it. Blend everything, add water, milk to taste and the desired creaminess (after blending them I pass them through a sieve to be very fine). Add double cream, salt, pepper to taste and at the end a little chopped fresh parsley. You can put the bread in the toaster to make some good and crunchy croutons. Good appetite !
