In a skillet over medium to high heat drizzle in the olive oil then saute the onion, garlic, celery, and mushrooms for 5 - 8 minutes.

Pour the cooked ziti, sauteed mushroom mix, marinara sauce, Worcestershire sauce, Italian herbs, mascarpone, fresh chopped basil, a pinch of salt and pepper, and half the parmesan into a large bowl and mix until it is all well coated.

Pour the mix into a 9 x 13-inch casserole dish and spread out.

Place the sliced mozzarella over the pasta and then sprinkle with parmesan. Bake in the oven for 25 - 30 minutes or until the cheese is bubbling.
