Slice the cremini mushrooms and dice the onion. Then, finely chop the fresh rosemary, thyme, and oregano.
Lightly spray a pan with olive oil spray. Add the mushrooms, onions, herbs, garlic, salt, pepper, and Worcestershire sauce to the pan. Saute until the onions are translucent and the mushrooms are cooked.
Move everything to one side of the pan to make room for the ground turkey. Add your ground turkey breast to the pan. Season both sides of the ground turkey with salt and pepper. Start to cook the turkey and use a spatula to separate it into tiny pieces. Then, combine the sauteed mixture until the turkey is fully cooked.
Whisk together the cream of mushroom soup and milk. Add this to the pan once the turkey is fully cooked. After that, combine all of the ingredients in the pan.
Transfer everything from the pan to an 11x7 oven-safe baking dish.
Sprinkle the light cheddar cheese on top of the casserole.
Top with the frozen tater tots. Bake the casserole at 400℉ for 20-25 minutes and enjoy!
