Prepare all ingredients as listed.
Make the meatballs: In a bowl, combine the ground beef, garlic, parsley, egg, breadcrumbs, parmesan, and black pepper. Mix everything thoroughly and form into small meatballs.
In a pan, heat the olive oil over medium heat. Fry the meatballs until they are browned on all sides. Once browned, add in the crushed tomatoes and Italian seasoning. Simmer until the meatballs are cooked through to an internal temperature of 160°F (71°C). Season with pepper to taste.
Meanwhile, cook spaghetti according to package instructions until al dente. Drain the pasta, reserving a small amount of pasta water if desired.
Add the drained spaghetti to the sauce and toss to coat evenly.
Heat the oil in a sauté pan over medium heat. Saute the green peas about 2–3 minutes until hot. Season with black pepper to taste.
Combine sparkling water and lemon slices. Serve over ice if desired.
Serve the spaghetti and meatballs with peas, lemon sparkling water and sliced pear.
