Cook spaghetti noodles according to the directions on the box.
Heat a skillet or frying pan over medium-high heat. When hot, add in the cooking oil, onions, carrots, and zucchini saute for 2 minutes.
Next, add in the ground meat and garlic and cook until the meat is no longer pink; drain (if you are using lean meat, skip the draining step).
Add the spaghetti sauce, hot sauce, Worcestershire sauce, salt, Italian seasoning, and pepper. Bring to a slight boil, then reduce heat; cover and simmer for 10 minutes or until heated through. Taste. If the sauce is bitter, add a pinch of sugar. Serve the meat sauce over spaghetti, and top with basil and Parmesan cheese.
