Preheat oven to 350F and line a baking sheet with parchment paper
Combine mini meatball ingredients in a mixing bowl
Take 1 tsp of meatball mix and roll into a small mini meatball and lay on the baking sheet
Repeat this process until you have used up all of the meatball mixture - if you don't have time to roll all of the meatballs you can roll several large meatball and cut them into smaller pieces one they're cooked
Bake the mini meatballs at 350F for 14 minutes
While the meatballs bake, combine small ring pasta, tomato puree, water, salt, onion powder, garlic powder, and paprika to a large pot or dutch oven
Heat over high heat until the mixture boils - stirring regularly
Once boiling, reduce to a simmer and cover the pot
Simmer for 10 minutes stirring frequently
Turn off the heat and while the pasta is still warm mix in the milk and cheddar cheese
Stir until the cheese is fully melted
Mix the mini meatballs into the SpaghettiOs and serve!
