Let me show you how I do it.
Cut off the top and also the bottom of the sqaush. (Make sure it can stand up on its bottom)
Using a peeler, peel the rind off all the way around the sqaush.
Scoop out the seeds and stands from the inside of each half.
If desiring to dice the squash into bite sized pieces, cut through each half into 1 inch strips, then cut the strips into 1 inch cubes.
Cook as recipe calls for.
