FOR THE SCALLOPS:
Heat olive oil over high heat in a skillet. Once the oil is very hot, place scallops in the skillet.
Allow scallops to sear until browned (about 2-3 minutes, or to your liking). Flip and sear the other side.
FOR THE BUTTERNUT SQUASH:
Poke holes with a fork in the squash.
Roast the whole squash for 1 hour at 400 degrees, or until soft.
Once cooled, de-seed and peel the skin off the squash.
Place into a food processor and process until smooth. (I add a bit of almond milk to get the right consistency)
