We do the same dish at my house only with a few differences.
Brown meat with Lipton beefy onion soup mix, drain.
Line pan with frozen tots, layer with beef, then use canned Lesure Peas, top with can of cream of chicken soup, top with shredded cheese. Then add about 1/4 cup milk over the top. It seeps to the bottom to cook the potatoes.
Spray the foil with Pam spray, cover dish with foil and cook for 45 minutes, Uncover and top with French fried onions and cook for an additional 15 minutes.
