Good news for your vegetable peeler: all squash skin is edible. Some squash skin certainly tastes better than others, it's a question of thin versus thick skin. The thicker the skin, the harder it is to chew making it less desirable to consume. Delicata, acorn, and dumpling squash all have skin that is thin enough to keep on. Don't think of keeping squash skin on as a shortcut either, it's highly recommended for flavor and texture.
Acorn squash skin becomes nutty and soft when cooked, you can compare the flavor and mouth feel with leaving the skin on a baked potato. This particular recipe combines nutty acorn squash with spicy red chile, yum!
