Place the chicken in a large resealable freezer bag.
Add the tater tots, bacon bits or crumbled cooked bacon, shredded cheese, evaporated milk, and seasonings.
Remove the excess air from the bag, seal, and freeze.
Thaw.
Spray your crockpot with nonstick spray or use a crockpot liner (these are a major mess saver!).
Dump the bag contents into the slow cooker.
Cover and cook on low for 4 hours.
*You can cube the chicken breasts or leave them whole.
