Dice bacon and cook in skillet until brown. Remove bacon to a plate lined with paper towel. Set aside.
Reserve 1 tablespoon grease from bacon, and drain remaining grease. Add apples and onion to skillet. Cook until apples start to soften, about 4-5 minutes.
Add cooked sausage, squash, Gateway to the North, sugar, and salt and pepper to taste. Stir to combine. Cook until heated through, adjusting seasoning as needed.
Add bacon back in and enjoy!
