Add ground beef to a pot on medium high heat, season with salt, pepper, and Italian seasoning, and cook until browned.
Add spinach, garlic, and salt and pepper (if needed) and cook until spinach is wilted. Then, add beef stock and bring to a boil until all sides are bubbling.
Add ½ cup (120 ml) heavy cream and stir. Then, add zucchini, green beans, broccoli, and pasta and stir until well combined. Cook for 15 minutes or until pasta is cooked and the sauce has thickened, stirring occasionally.
Turn off the heat, add remaining ¼ cup (60 ml) heavy cream and stir for a creamier sauce.
