Ginger- and scallion-laced meatballs sit atop a mound of pasta dressed in a sweet-and-tangy red sauce.
Preheat oven to 425˚F.
Combine meatball ingredients in large bowl and roll meatballs like large golf balls and arrange on parchment-lined baking sheet. Bake 10 minutes, spoon a dot of sauce (see below) on each meatball and return to oven to glaze 5-7 minutes more.
Heat a pot of water to boil for udon or spaghetti, and salt water if using spaghetti.
In a large skillet, combine the sauce ingredients and bring to a simmer over medium heat. Spoon a bit of sauce over meatballs and return them to oven.
Cook noodles or spaghetti 1 minute less than package directions. Add about ¾ cup water to sauce, then drain pasta and toss with sauce.
Serve noodles or spaghetti with meatballs on top and garnish with topping or toppings of choice.
