Greek Salad Pizza

Fridays are traditionally pizza night at our house.  But I like to mix it up a little and make pizza that is just a little unusual once in a while.  Tonight I had all the ingredients for a good Greek salad so I thought...hmm..why not on a pizza?  I used my own homemade pizza crust but you could use whatever you like...
This is it before baking:

My pizza crust recipe:
1 T. yeast
dissolve this in 1 c. warm water.  Whisk well.
Now whisk in:
1 T. olive oil
1 t. honey or sugar
1 t. salt
Stir in:  3-4 c. bread flour until it forms a not so sticky ball.  Knead for several minutes.  Roll out into a circle shape and place on a pizza pan.
Top the dough with 2-3 T. balsamic salad dressing
Then in a food processor blend:
3 cloves garlic
3/4 can garbanzo beans -drained
This will make a substance much like humus.  Spread this mixture on top of the balsamic dressing.

Top the humus mixture with
2 c. fresh spinach
1 c. slied kalamata olives
 2 sliced tomatoes
remainder of the can of garbanzo beans
On top of this sprinkle:
1 c. feta cheese
1/2 c. Parmesan cheese
1/2 c. mozzarella cheese
Then bake the pizza at 400 degrees for 15 minutes.  When it comes out of the oven, sprinkle on some tazaki.
Make the tzaki by blending 1 c. cucumber with 1 c. plain greek yogurt and 1 t. oregano.
