Heat oven to 400°F (200°C). Line a 12-cup muffin tin with liners or grease well. For a golden crust, lightly oil each cup.
In a large bowl, combine cornmeal, flour, baking powder, baking soda, salt, pepper, sage, and thyme. Whisk to evenly distribute leaveners and spices.
In another bowl, whisk buttermilk, Greek yogurt, eggs, olive oil, and honey until smooth.
Pour wet into dry. Stir just until a few flour streaks remain—no overmixing unless you enjoy bricks.
Add cheddar, turkey sausage, corn, scallions, and red pepper flakes if using. Fold just to distribute.
Divide batter evenly among cups, filling about 3/4 full. For extra cheesy tops, sprinkle a pinch of cheddar over each.
Bake 14–18 minutes, until tops are golden and a toothpick comes out mostly clean (a touch of melted cheese is fine).
Let rest in the pan 5 minutes, then transfer to a rack. They set as they cool, so resist the grab-and-burn instinct.
Enjoy warm with a dab of butter, hot honey, or a swipe of cranberry relish for classic Thanksgiving vibes.
