Using clean hands, grab a portion of the meat mixture and form it into a ball, rolling it between your hands. You should be able to make 12 or more small meatballs. Set meatballs (once formed) onto a plate or wax paper.

Heat 1 Tablespoon oil (vegetable or olive) in a large non-stick skillet. Heat on medium until oil and skillet are hot (but not smoking). Add meatballs. They should sizzle as they hit skillet. Cook until brown on bottom, then carefully turn over. Continue to cook until all sides are brown (meatballs do NOT have to be completely cooked through - they will finish cooking in sauce later). Transfer to paper towels to drain.

In a separate large saucepan, heat up spaghetti sauce (enough sauce for 4 servings) on medium-low. Carefully add meatballs to sauce. Spoon sauce over the top of each meatball. Let meatballs and sauce continue to cook on medium-low for about 30 minutes, occasionally spooning more sauce over the meatballs as they cook.

When meatballs are halfway through cooking time, cook spaghetti noodles in separate pan, according to package directions. Drain. When done, remove meatballs from spaghetti sauce (keep warm). Mix cooked, drained noodles with the hot spaghetti sauce. Serve up the pasta onto individual plates or into bowls. Spoon any leftover sauce onto pasta. Top each serving with 3 meatballs. Garnish with grated Parmesan cheese, and serve!
