   Transfer to a wire rack set over an aluminum foil-lined baking sheet, spacing at least an inch apart, and brush with 1/2 Celsius sauce.

   Bake until meatballs are browned and cooked through, about 20 minutes. Remove from oven and brush with additional 1/2 Celsius sauce. .
5. 5
   Top each meatball with a piece of provolone cheese and allow to melt.
6. 6
   To assemble sliders, brush top and bottom of mini brioche buns lightly with sauce. Place a few baby spinach leaves on the bottom half of each bun. Top with a meatball, followed by the top half of the bun. Spear each slider with a toothpick, and serve immediately.
