Begin by cooking the frozen chicken tenders according to package instructions, typically baking at 400°F (200°C) for 20-25 minutes until golden brown.

While the chicken cooks, slice the mozzarella cheese into fun shapes resembling sharp teeth.

Take the green olives stuffed with pimento and skewer them onto toothpicks, placing two olives on each to create the 'eyes'.

In a small saucepan, heat the marinara sauce over medium heat, stirring occasionally to warm through for about 5 minutes.

To assemble, place the bottom half of each slider bun on a clean surface, spoon warm marinara onto each bun, and add a crispy chicken tender.

Add additional marinara over the chicken, then place the cheese 'teeth' on top, followed by the top bun.

Gently insert the skewered olives into the top of each slider to resemble spooky eyes.

Serve immediately on a festive platter while warm and melty.
