Heat a large non-stick skillet over medium high heat and add olive oil.
Lay chicken tenderloins down in hot oil. Season with ⅛ teaspoon each sage, thyme, celery seed, salt and pepper. Sear tenderloins on each side until nice caramelization appears. Remove tenderloins from pan and place in 9x13 casserole dish, spread evenly across the bottom.
Return skillet to heat and add chopped onion. Saute until translucent and add sliced mushrooms and minced garlic. Saute until mushrooms are soft.
Add butter. Combine until thoroughly melted.
Add uncooked rice. Season rice and vegetable mixture with approximately ¼ to ½ teaspoon each of sage, thyme, celery seed and pepper. Stir to combine thoroughly.
Pour rice and vegetable mixture over tenderloins, spreading evenly with a wooden spoon.
Add approximately 4 cups chicken broth. Cover with tin foil and bake for approximately 1½ hours or until liquid is absorbed and rice is al dente.
Serve topped with shredded mozzarella cheese.
Notes
If pan is dry after tenderloins are seared, add a little more oil to pan to saute vegetables. Measurements of herbs are approximate amounts.
