Preheat your oven to the temperature recommended on the flatbread packaging (usually around 400°F/200°C).

Cook Italian Sausage:

In a skillet over medium heat, cook the ground Italian sausage until browned and cooked through. Break it up into crumbles as it cooks. Drain any excess grease if necessary.

Prepare the Flatbread:

Place the store-bought flatbread on a baking sheet or pizza stone.

Spread Marinara Sauce:

Spread the marinara sauce evenly over the flatbread, leaving a small border around the edges for the crust.

Add Cooked Sausage:

Sprinkle the cooked Italian sausage crumbles evenly over the marinara sauce.

Cheese Layer:

Sprinkle the shredded mozzarella cheese over the sausage. Add fennel seeds to taste, adjusting based on your preference for the licorice flavor.

Optional Toppings:

If you're using red onion, scatter the thinly sliced pieces over the pizza.

Parmesan Finishing Touch:

Sprinkle the shredded Parmesan cheese over the top for an extra layer of flavor.

Bake:

Place the baking sheet or pizza stone in the preheated oven and bake according to the flatbread package instructions or until the cheese is melted and bubbly, and the edges of the flatbread are golden brown.

Serve:

Once out of the oven, let the flatbread pizza cool for a couple of minutes before slicing. Serve hot and enjoy!

Feel free to customize the recipe based on your preferences. You can add other toppings like olives, cherry tomatoes, or fresh basil for added freshness.
