New Years Eve I made a wonderful taco pizza.  My kids loved it, my husband loved it, and the dog loved what the baby dropped!
It is really good and the crust doesn't take anytime at all to make.

Taco Pizza
1 Homemade crust (recipe to follow)
1 pound of ground beef
1 can black beans (rinsed and drained)
1 package of your favorite taco seasoning
3/4 cup of water
1 to 1 11/2 cups of salsa
1/2 head of lettuce, chopped into bite sized pieces
2 cups of cheddar cheese
1/4 cup taco sauce

Preheat oven to 450.  Pat out pizza crust onto a large pizza stone.  (I use the large sized one from Pampered Chef). Take the crust all the way to the egde of the stone.  Spread the salsa on the unbaked crust.
Brown the ground beef and drain.  Mix in the rinsed and drained black beans, packet of taco seasoning, and water.  Cook in a skillet until water is gone. 
Spread this mixture onto the crust and salsa.  Sprinkle with 1/2 cup of cheese.
Bake until the crust is done, 15 to 20 minutes. 
Sprinkle lettuce over pizza, top with the remaining cheese and taco sauce.

Pizza Crust
1 packet of yeast
1 cup of water
1 tablespoon of sugar
3 cups of whole wheat or plain flour
1 teaspoon of salt

Mix yeast and warm water with sugar until dissolved.  Let stand 5 to 10 minutes.  If the mix has bubbles or froth on the top, then add the salt and 2 cups of flour.  If not, allow it to stand another 5 to 10 minutes.  (If after 20 minutes it has not shown any changes, discard and begin with new yeast.
Stir until flour is completely mixed in. 
Turn onto floured surface and knead and add flour until you have a smooth dough - about 5 minutes. Let rest while you are preparing your other pizza ingredients.
This makes 1 large crust.

Enjoy!
