I'll second the pizza stone. Definitely makes home made taste like it came from a pizzeria. I have also gone back and forth on pizza. Basically if I really need to drop some pounds it comes off the menu, like Cassie said I haven't found a way to cut the calories w/o ruining the taste.
But when I am just making sure I eat healthy, I make the crust in my bread machine - 30% whole wheat and I usually add milled flax (unbeknownst to DH - he thinks he doesn't like it
) for a nutritional boost. We almost always make "white pizza" - no tomato sauce. Skim ricotta and mozzerella help keep the fat down but makes for a lovely creamy texture that goes well with a pile of veggies.
It really can be a healthy meal, you just have to watch the protions
