To make the meatballs:
Finely dice 1/4 of the chopped green pepper.
Mix minced garlic, ground beef, 1/4 cup basil, diced green pepper, and a pinch of salt and pepper until well combined.
Using your hands, form mixture into small golf ball size rounds.
Place meatballs in a semi-dish roasting pan. Add tomato halves and remaining green pepper. Drizzle with oil and a pinch of salt.
Roast under 375 F until meatballs are well cooked through (about 25 minutes).
Remove from heat.
Use a medium size bowl to mix meatballs with 1/4 of the pasta sauce. Mix until evenly coated
To make the Spaghetti:
Heat a large pot of boiling water with a pinch of salt. Add pasta and cook until pasta is soft (about 15 minutes).
In a colander drain pasta well and let cool slightly.
Add remaining 3/4 of the pasta sauce to a large bowl and mix with well drained spaghetti until evenly coated. Add in tomatoes and green pepper and toss.
Serve spaghetti into separate bowls. Add 3-4 meatballs and sprinkle on parmesan cheese to your liking.
