How to Make
Start by making sure the veggies and chicken are all prepped and preheating the oven to 350 degrees Fahrenheit.
Simply mix all of the ingredients, except the breadcrumbs), together in a large mixing bowl.
Transfer the mixture to an oven safe casserole dish.
Bake for about 50-60 minutes, until the top is golden brown and bubbly. In the last 10 minutes of baking, sprinkle the breadcrumbs over the top. Enjoy!
Storage and Freezing
For any leftovers, place them in an airtight container in the fridge for up to 3 days.
Because of the mayo and cream of mushroom soup, I would only freeze this recipe after it's been baked. Freeze it for up to 3 months!
Thaw it in the fridge the day before serving, then heat it in the oven at 350 degrees Fahrenheit until the desired temperature is reached.
