Preheat the oven to 450° F.
To marinate chicken, place olive oil, the juice of one lemon, and lemon pepper seasoning into a storage sized zip bag and mix well to combine. Add in the chicken and mix/shake well to coat the chicken, marinating in the fridge for 30 minutes to an hour.
Wash and chop asparagus, taking 2 inches off of the bottom (thicker) end, and lay asparagus (without overlapping) on a foil-lined baking sheet. Toss in olive oil, salt, and pepper until evenly coated.
Place chicken (keeping reserved marinade) in the center of the pan next to the asparagus. Drizzle the remaining marinade over the chicken and asparagus to impart flavor!
Bake for 20 minutes or until chicken is no longer pink in the center of the thickest piece, and its juices run clear.
While the chicken and asparagus are roasting, chop up button mushrooms and 2 cloves of garlic.
In a sauce pot on medium heat on the stove, add 5 cups of chicken broth, the risotto mix, and garlic.
Bring to a boil and then simmer uncovered on medium-low heat for 18 minutes.
Add the quartered mushrooms about 5 minutes into simmering, adding more liquid if needed, and stirring occasionally.
Finish with butter and cheese!
