Question: how to cook frozen chicken breast in toaster oven?
Answer: Preheat oven to 375. Spray baking dish with non-stick spray. Place frozen chicken breast in dish. Top with sauce. Bake for 45 minutes. Options: Add veggies for a one dish meal. If using cheese, put it on the last 2 minutes of cook time. This gives it time to melt and brown if you like it that way.
