Cut the lavash bread in half lengthwise and arrange on a baking sheet. Brush the top of each lightly with oil and bake at 400°F for 3-4 minutes or until edges are beginning to crisp.
Remove the bread from the oven and layer with pesto, shredded mozzarella, raw Italian sausage, giardiniera, fresh mozzarella, and ricotta. (*I use wet fingers to pinch off small pieces of Italian sausage.)
Return to the oven and bake at 400° F for an additional 5-6 minutes, until cheese is fully melted and sausage is cooked through.
Sprinkle with grated parmesan cheese and other garnishes as desired.
*If you prefer to use cooked sausage, add the raw sausage to a small skillet and brown over medium heat, crumbling the sausage with a spatula, until cooked through.
