Peel and cut into bite sized pieces 4 potatoes. Clean and divide cauliflower into small sections. Peel and dice 1 med onion. Dice carrot finely. Boil potato in just enough water to cover. Boil or microwave cauliflower, onion, & carrot just until cauliflower is tender. Use as little water as possible. When potatoes are tender, mash lightly, leaving some chunks left unmashed. Do not drain water. This is what makes the soup thick.
Add the cauiliflower, onion, and carrot. Add salt and pepper to taste. (I like a little garlic powder also).
If soup is too thick, add a little more water. Simmer for about 25 minutes more.
I do not know the exact nutritional information.
