How to Make It
Preheat oven to 475°F.
Heat oil in a large skillet over high heat. Add salt and butternut squash; cook 2 minutes, stirring occasionally. Reduce heat to medium-high and cook 5 minutes, stirring occasionally. Combine 1 cup chili and 3 tablespoons flour in a bowl; add to pan. Add remaining 4 cups chili to pan; bring to a simmer. Spoon chili mixture into an 8-inch square baking dish coated with cooking spray.
Combine remaining 1 cup flour, cornmeal, and baking powder in a bowl. Cut butter and cheese into flour mixture using a pastry blender or 2 knives until mixture resembles coarse meal. Stir in buttermilk just until combined. Drop flour mixture evenly over chili to form 24 biscuits (about 2 teaspoons each). Bake at 475°F for 15 minutes or until biscuits are golden brown. Sprinkle with parsley, if desired.
