Saturday is Pi Day, and the celebration is extra special this year. The holiday honoring the ratio of a circle's circumference to its diameter -- the first five digits of which are 3.1415 -- falls on 3/14/15.

So how should you recognize this Super Pi Day? By eating pie, of course. But you have to make it first, which can be a time-consuming and difficult process.

The trick is to use a premade crust. They taste nearly the same as homemade and save so much time. Check out rolled-up Pillsbury pie crusts, Keebler's graham cracker crust or Nabisco's Oreo crust, all of which should cost about $3 at your local grocery store.

Once you've got your pie shell in order, try one of the super simple recipes below for a delicious, mathematically punny treat:

Cherry pie: Prepare crust as directed. Fill with two, 21-ounce cans of cherry pie filling. Bake for 40 minutes at 425 degrees.

Blueberry pie: Prepare crust. Mix together 6 cups of blueberries with 1/3 cup of tapioca, orange juice and 1 1/4 cups of sugar. Once they're well combined, spoon the filling into the crust and bake for 45 minutes.

Banana cream pie: Prepare crust as directed, lining the bottom with banana slices. Then beat together 2 1/2 cups milk with two packages of instant vanilla pudding. Add 1 cup of Cool Whip and pour mixture into crust. Put another banana's worth of slices on top, then refrigerate for at least three hours.

Lemon ice box pie: Prepare crust as directed. Mix together 1 can of sweetened condensed milk, 1/2 cup of lemon juice and 1 tub of Cool Whip. Transfer into crust, then refrigerate for at least an hour.

Chocolate pudding pie: Prepare crust as directed and cool. Beat together two packages of chocolate pudding mix and 2 3/4 cups of cold milk, and pour it into the crust. Refrigerate for at least an hour and spread 1 cup of whipped cream on top when ready to serve.
