Mashed "Potatoes" - 2 points per serving

This is from Weight Watchers - it's 2 points per decent sized serving, the recipe makes 4 servings.
The best part is, you really don't need ANY extra butter on these babies!  maybe a little extra salt, but that's it!

Ingredients
8 oz cauliflower, fr3esh, or frozen, raw, florets
3 small yukon gold potatoes, uncooked, peeled, cut into small pieces for boiling
2 cloves garlic - fresh, peeled
1 tsp salt, table, divided (I use more than this!)
1/4 cup milk (lowfat or light)
2 tspButter, regular, with salt
pepper to taste
chives to taste

Directions
Place cauliflower, potatoes, garlic and 1/2 tsp of salt in medium saucepan and add enough water to cover.  Bring to a boil and cook until vegetables are tender (about 10-15 minutes).  Drain and return to pan.

Stir in milk, butter, a bit more salt, pepper, and mash with potato masher until smooth.  Stir in chives and serve. 

This says it yields about a half cup per serving, and maybe I used more cauliflower than called for, because I get close to a full cup per serving.
