In a large pan or deep skillet, add the box of Pronto spaghetti and cover with 3 cups cold water; add a pinch of salt if using.
Bring the water to a boil over high heat, then reduce heat slightly to maintain a steady boil; cook uncovered until the water is mostly absorbed and the pasta is al dente, about 8–10 minutes—watch and stir occasionally.
While the pasta cooks, heat a large skillet over medium-high and add the ground beef.
Cook the beef, breaking it up with a spatula, until browned and cooked through with no pink remaining, about 6–8 minutes.
Stir the jar of tomato and basil sauce into the cooked beef and heat for 1–2 minutes until warmed through.
When the pasta is done and most of the water is absorbed, add the meat sauce to the pan with the pasta and toss gently to combine; alternatively plate the pasta and spoon the sauce over individual servings.
Serve immediately, garnished with chopped fresh basil and freshly grated Parmesan if desired.
