*Prepare Dough*
In a small bowl, combine water, yeast and sugar and stir well to combine. Set aside for 5 minutes. In a large mixing bowl, combine flour, semolina flour and salt. Add olive oil to the yeast mixture. Stir well and add to flour. Add additional half cup warm water. Bring the mass of dough together until a compact ball is formed. Turn dough out onto work surface and knead vigorously for 7 minutes until smooth and satiny. Place a small amount of olive oil in a large bowl. Put dough in the bowl and turn it twice to coat. Cover bowl with plastic wrap and a kitchen towel. Set the bowl in a warm place. Allow dough to double in bulk, about 1 hour. Punch down dough and let stand for 20-30 minutes at room temperature before using. Roll dough into a circle about 25 cm in diameter, building up the edges slightly. Place dough on a pizza pan or baking sheet.
*Prepare Toppings*
Coat chicken with jerk seasoning. Heat olive oil in a saute pan and when hot, sear chicken on both sides. Remove chicken from pan, add mushrooms to pan and saute them for about 1 minute. Drain liquid from pan. Slice chicken into thin strips. Prepare Salsa: In a small mixing bowl, combine and mix thoroughly all salsa ingredients.
*To Assemble Pizza*
Spoon barbecue sauce onto dough. Top with mushrooms and chicken strips. Sprinkle cheeses on top. Bake pizza in a preheated 450'F oven for 7-8 minutes until crust is browned and cheese is golden and bubbly. Garnish pizza with mango salsa as soon as pizza is removed from oven.
