Preheat oven to 350 degrees and line a baking sheet with foil
Slice your squash lengthwise and remove seeds using a spoon
Poke a few holes in the outside of the squash and drizzle with a bit of olive oil
Place squash halves on baking sheet and roast for 35-45 minutes until fork tender
Allow the squash to cool and prepare your premade pie crust according to directions
Once the squash is cool scoop out the flesh / remove the skin and set aside
In a food processor combine the eggs, milk, squash and vanilla and process until smooth
Next, add in the sugar and spices and blend until smooth
Pour the squash mixture into the prepared pie crust, you may have some extra so be careful not to overfill the crust
Bake the pie in the oven at 350 degrees until just set in the middle and puffed up, it should be about 45 - 50 minutes, but can vary based on your oven. It will look just toasted/cooked on the edges & crust
