Try this site for freezer crock pot meals. You might also want to give her a plastic shoe box to thaw them in the fridge as most need to sit in the refrigerator for 24 hours to thaw. Then she can just put them in the crockpot in the morning. Do NOT put the plastic bags into the pot. If she doesn't have a crock pot that can be timed then the sons can switch it to warm at the end of the day so things don't overcook.
