"flatout" bread makes a decent crust and it is only 1 or 2 points for a big personal pizza crust. With a little sauce and 2% mozzarella plus veggies - Mmm!
If you have a bread machine, you can easily make dough for a good whole wheat or partly whole wheat crust as well. Let me know if you want the recipe.
The Lean Cuisine pizzas are my favorite of the "diet" supermarket pizzas. I especially like the one with spinach and mushroom. 6 points.
