Shepherds pie with turkey and a green salad on a white plate


Honor Pi Day with Shepherd's turkey pie recipe

  • March 14 marks Pi Day, an annual celebration of the mathematical sign pi.
  • Turkey is high in protein, loaded with B vitamins and nutrients such as zinc and iron.

March 14 marks Pi Day, an annual celebration of the mathematical sign pi. Pi Day was founded in 1988 by physicist Larry Shaw. March 14 was selected because the date (3.14) represents the first three digits of pi.

In honor of March 14, Pi Day, here’s a recipe for a yummy, comforting turkey shepherd’s pie. Turkey can be enjoyed year round, not just at the holidays. You can also use chicken, ground meat or plant-based protein. To save time you can also use frozen mashed potatoes.
