Preheat oven to 400°F.
Slice the top off the garlic bulb, set on a square of aluminum foil and drizzle with olive oil. Wrap the foil around the garlic bulb, place on a foil lined baking pan, and bake for about 40 minutes, or until the garlic is soft enough to pierce easily with a knife. Let cool slightly and remove all the roasted garlic cloves.
Bring a pot of water to a boil and cook the pasta according to the package directions.
While the water is coming to a boil, heat 1 Tablespoon olive oil in a saucepan and add the roasted garlic. Smash garlic with a potato masher or fork. Cook for 2 minutes. Add crushed tomatoes, dried onion, and Italian seasoning. Season with salt and pepper to taste. Bring to a bubble then reduce to low and simmer until the pasta is cooked.
Heat 1 Tablespoon olive oil in a skillet over medium high heat. Add zucchini, 2 teaspoons garlic powder, and season with salt and pepper. Sauté until zucchini is cooked and browned slightly, about 5-7 minutes.
Heat shredded pork either in the microwave or in the same skillet as the zucchini.
Serve pasta topped with sauce, zucchini, and shredded pork.
