Preheat oven to 350°.Spray a mini cupcake pan with non-stick spray and set aside.
Cook pasta to al dente according to the package directions.
Place cooked pasta in a medium-sized bowl to cool.
Add egg, cheese, and seasonings to the pasta and stir until completely incorporated.
Using your fingers, press 2-3 tablespoons of the pasta, egg, and cheese mixture into each of the cupcake holes.
Use a shot glass or the back of a wooden spoon handle to press the pasta down so there is an indent like a small nest.
Bake the pasta nests for 15-20 minutes until they are firm and just starting to brown on the bottom.
While the pasta nests are baking, add the pasta sauce and meatballs to a stove-top pan and simmer until fully warmed.
Remove the pasta nests from the oven and let them cool for 10 minutes.
Top each one with an individual meatball and a fancy toothpick to hold them in place.
Drizzle each meatball with a little more pasta sauce.
Serve warm or at room temperature.
