Fits the Feingold Diet: Hawaiian Pizza Alfredo

Stage One of the Feingold Elimination Diet takes out a lot of fruits and veggies with salicylic acid since some kids can definitely have a sensitivity to these foods.  One of these foods is the tomato.  Oh, how we have missed the tomato!  Little did I realize how often I made Italian or Mexican dishes in the past, all of course showcasing the tomato.  A few weeks ago, the Drama Queen asked me if there was a way we could still have pizza.  "Well, honey, we can't have tomatoes right now," was my immediate answer, but then I thought, "Why not try making a white pizza?"  And here, my friends, is the result - hawaiian pizza alfredo.
For the dough, you need:
   1 cup lukewarm water
   1 TBS active dry yeast
   1 TBS oil
   1 tsp salt
   2 1/2 to 2 3/4 cups unbleached all-purpose flour
For the alfredo sauce, you need:
   4 TBS butter
   4 TBS unbleached all-purpose flour
   dash of salt
   dash of black pepper
   2 cups milk
   1/3 to 1/2 cup Parmesan cheese
For the toppings, you need:
   1 can pineapple chunks, drained (save juice for cooking the chicken)
   1 lb cooked boneless skinless chicken breast, cut into small cubes and cooked in the pineapple juice until no longer pink
   2 - 3 cups of shredded cheese (I used colby jack, but mozzarella would work well too)

Okay, let's make a pizza! (well, two actually...)
     Make your pizza dough first by adding the yeast to the lukewarm water and letting it sit for a couple of minutes.  Then add in the oil, salt, and 1 1/4 cups flour and mix well.  Keep adding the rest of the flour until you have a soft dough that pulls away from the sides of the bowl.  Turn dough out onto a floured surface and knead for six minutes until dough is smooth/elastic.  Put your dough into a large greased bowl, turn the dough over to grease the dough, and cover bowl with towel.  Put the bowl in a warm place for the dough to rise until doubled (about 80 to 90 minutes).  (I turn my oven on its lowest setting for 10 seconds and then turn it off.  The inside of the oven is then the perfect temperature for allowing the dough to rise.)  Next, turn the dough out onto a floured surface and divide into two equal pieces.  Roll each piece into a smooth, even rectangle onto a cookie sheet.
     Preheat the oven to 425 degrees.  While the oven is heating, make your alfredo sauce.  Melt the butter in a saucepan over medium heat.  When completely melted, add the flour, salt, and pepper, and whisk until completely combined.  Pour in the milk and whisk constantly until the mixture starts to thicken.  Add the Parmesan cheese to your taste and stir to combine.  If sauce is too thick, add a little more milk.  Remove sauce from heat and immediately spread it over your pizza crusts.
     Sprinkle the shredded cheese over the alfredo sauce and then add the chunks of pineapple and chicken pieces evenly over the pizzas.  Bake in the oven at 425 degrees for 15 - 18 minutes, when the crust edge is lightly browned and cheese is melted.  (The center of the pizza may seem a little soft and underdone, but it is just the alfredo sauce).

Wait a few minutes, then slice up into squares and enjoy!
