Cut acorn squash into slices (I used the grooves as my cut lines) and scoop out the seeds and discard. Place each slice flesh side up on the baking sheet.
In a microwave save dish, melt the butter with the honey and pumpkin pie spice. Drizzle melted mixture over the squash and make sure all of the flesh is coated.
Bake for 40 minutes, and enjoy!
