Place a whole butternut squash in a 400 degree oven for 30 minutes to soften it slightly. (This step is optional, but makes the squash easier to cut.)
When the squash is cool enough to handle, use a peeler to skin the whole squash and cut it into cubes.
Put the cubed squash onto a baking sheet, drizzle melted butter, olive oil, honey, and sea salt, and then stir to combine (Or let the kids get in there to mix it up with their hands!)
Roast at 400 degree oven for 30 minutes, turning the cubes halfway through for even browning.
