Cook spaghetti noodles according to the directions on the package, rinse with cold water and mix with 2 eggs.

Spray the inside of the larger bowl and the outside of the smaller bowl with non-stick cooking spray.

Place about 1/4" of spaghetti noodles in the bottom of the larger bowl and place the smaller bowl into the center of the larger bowl.

Continue wrapping spaghetti noodles around the smaller bowl — between the two bowls — until they reach the top of the smaller bowl.

Bake at 350° for 30 minutes.

Remove the smaller bowl by twisting it and then flip the larger bowl upside down and remove your finished spaghetti noodle bowl. If the noodles are still sticking to the glass bowls you may need to trace around the bowls with a knife to help loosen them.

Cook meatballs according to the directions on the package and mix with spaghetti sauce.

Fill spaghetti noodle bowls with meatballs and top with Parmesan cheese.
