Preheat the oven to 375F.
In the bottom of the casserole dish, add the chicken stock and cream of chicken soup mix.
Use a whisk to combine.
Add in both rice and pasta blends, again whisking until combined and all of the contents are wet.
Pour the chopped frozen broccoli on top of the rice mixture, covering the entirety of it.
Lay the raw chicken tenders on top of the broccoli layer in the way that best fits all of the chicken.
Dust the top of the chicken with old bay seasoning (or your choice of general chicken seasoning).
Spread the shredded cheese over the top of the chicken, cover with tinfoil.
