Dice squash into ½-inch cubes.
Toast pecans. Melt butter in heavy large skillet. Add onion and sauté until very tender, about 15 min. Add squash and toss to coat.

Re-warm over med heat before continuing. Stir in half of pecans and half of parsley. Add sea salt and pepper to taste. Transfer to bowl.
Sprinkle with remaining pecans and parsley before serving.
