- Preheat oven to 425°F. Line a large, rimmed baking sheet with parchment paper. Cut butter into 1/2-inch cubes and place on a small plate; return to refrigerator until ready to use. To a glass measuring cup or small bowl, add 3/4 cup milk and vinegar; stir to combine. Let stand at room temperature for 10 minutes.
- In a large bowl, whisk together 1 3/4 cups flour, cornmeal, baking powder, baking soda and 1/4 tsp salt. Using a pastry cutter, fork or your fingers, add butter cubes to bowl and work into flour mixture until it reaches a loose, sandy consistency with pea size chunks of butter remaining. Add milk mixture and stir gently with a rubber spatula until dry ingredients are just moistened. Stir in scallions and piquillos.
- Transfer dough to a lightly floured surface. With floured hands, quickly shape into a thick disk. Lightly sprinkle dough with flour and roll out to approximately 3/4 inch thick. Using a 3-inch cutter, stamp out biscuits and transfer to prepared baking sheet. Gather remaining dough and re-roll to make a total of 8 biscuits. Bake in center of oven until a toothpick comes out with a few moist crumbs and bottoms are golden brown, 11 to 13 minutes. Cool on baking sheet for 3 minutes, then transfer to a cooling rack.
- Meanwhile, mist a large skillet with cooking spray and heat on medium-high. Add sausages, turkey and thyme and cook, stirring occasionally and crumbling the meat into bite-size pieces, until no longer pink, 5 to 7 minutes. Meanwhile, in a large bowl, whisk together remaining 1 ⁄ 3 cup flour, remaining 2 3/4 cups milk, remaining ⁄ tsp salt and black pepper until smooth. To skillet, add flour-milk mixture and bring to a simmer on medium-high, stirring occasionally.
- Reduce heat to medium-low and simmer, stirring frequently, until thickened, 3 to 5 minutes. Split biscuits and place 2 halves on each of 8 plates. Over bottom half of each biscuit, spoon about 1/2 cup sausage gravy and top with eggs (if using). Sprinkle with chives and rest top halves of biscuits over gravy.
