Preheat your oven to 375°F (190°C). Bake the frozen chicken tenders on a baking sheet according to package instructions until golden brown (15-20 minutes).
While the chicken cooks, slice the slider buns horizontally while keeping them connected. Place the bottom halves in a baking dish and spread marinara sauce over them.
Once cooked, layer the chicken tenders on top of the marinara-sauced buns and place mozzarella slices over each tender.
Halve the green olives and place two halves on each cheese slice for the 'eyes'.
Place the top halves of the slider buns over everything and bake uncovered for another 10-15 minutes until the cheese is melted and bubbly.
Let cool for five minutes before slicing apart and serving warm.
