Preheat oven to 350*F. Line a baking sheet with parchment paper, or with aluminum foil and coat with cooking spray.
In a large bowl combine sirloin, breadcrumbs, cheese, egg, Italian seasoning, garlic and salt. Roll into 1 inch meatballs and place on baking sheet. Baked until cooked through, shaking pan every 5 minutes for even browning. Cook time is 10-15 minutes.
While meatballs are baking, cook spaghetti according to package instructions. Once drained, pour Tantillo Marinara Sauce over pasta, and warm on medium heat. When meatballs are done, toss into spaghetti and sauce.
Plate, garnish with basil and serve. Buon Appetito!
