Preheat your oven to 350, and get out your glass baking dish.
Cut chicken tenders in half and place them in the baking dish.
Sprinkle your dry packet of ranch dressing over the chicken. Try making sure it is as even as possible across the dish so that each piece of chicken gets some coverage.
Distribute half of the diced Peperoncini peppers across your chicken. Then pour half of the juice from that same jar across the whole pan.
Cut off a small slab of butter for each piece of chicken and lay them on top.
Cover the entire pan with the shredded cheese of your choosing.
Cover the pan with foil and place in the oven.
Cook for 35 minutes.
Take the pan out and remove the foil. Place back in the oven for 5 more minutes.
Serve over rice with a side of veggies.
