Preheat your oven to the temperature indicated on the chicken tenders package, typically around 400°F (200°C). Arrange the frozen chicken tenders on a baking sheet lined with parchment paper. Bake for approximately 20-25 minutes, flipping halfway, until they are golden brown and crispy.

While the chicken cooks, slice mozzarella cheese into rectangular pieces. Use a knife to carve jagged edges into the slices, creating a 'teeth' effect for the sliders.

Take a handful of green olives stuffed with pimento and skewer two olives per toothpick to turn them into monster eyes.

In a small saucepan, pour in your marinara sauce and place over medium heat. Stir occasionally until the sauce simmers, about 5-7 minutes.

Begin building your sliders by taking a slider bun and placing it on a clean surface. Spread about 1 tablespoon of warm marinara sauce on the bottom bun. Layer a crispy chicken tender on top, followed by another spoonful of marinara if desired, then fashion a mozzarella cheese slice with 'teeth' on top.

Place the top bun over your assembled slider. Carefully poke the two olive eyes through the top bun.

Serve warm for maximum enjoyment.
