Preheat over to 450F. Cut pizza dough in half. Stretch pizza dough into rectangles on a floured surface. Put parchment paper on baking sheets and place pizza dough on sheets. Bake in oven until brown in spots about 8-10 minutes.
Meanwhile heat 1 Tbsp olive oil in a medium skillet over medium-high heat. Add the sausage and cook until no longer pink breaking up into pieces with a wooden spoon, about 4 minutes.
Sprinkle the crust with the cheese, top with the sausage and garlic. Return the pizza to the oven and bake until the cheese is bubbly, 5-8 minutes. Sprinkle with the oregano.
Meanwhile, make the salad. Soak the red onion in ice water for 10 minutes, then drain. Toss the spinach, fennel, red peppers, artichoke hearts and red onion in a large bowl with the vinegar and 1 Tbsp olive oil, season with salt and pepper.
Top the pizza with the salad and cut into pieces. Sprinkle with red pepper flakes. Enjoy!
Spray two cooking sheets with cooking spray. Divide pizza dough and shape into approximately 8x12 oblong shape. Place on prepared cooking sheets, brush the dough with olive oil. Precook crust for about 5 minutes.
Using a grill pan, brush the pan with olive oil. Working in batches grill the pineapple, scallions, and ham, turning as needed, until lightly charred. Transfer to a plate as each batch is done. Cut the ham slices in half if desired.
Top precooked crusts evenly with cheeses, ham, scallion, and pineapple. Place in oven for about 5-6 more minutes or until crust is cooked through and cheese melts. Slice and enjoy!
