Add pasta, garlic, salt, pepper, olive oil and water to a large skillet. Bring the pan to a boil over high heat. Cook pasta, stirring constantly, about 5 to 6 minutes. Add broccoli and butter and cook, stirring constantly for another 2 to 3 minutes. Lower heat to low and mix thoroughly. Add heavy cream and Parmesan cheese and cook for another 3 minutes. Season with salt and pepper, to taste. Serve with more cheese if desired.
