Lazy meal example for me:
In the morning, frozen diced potatoes, frozen diced onions, frozen crinkle carrots, frozen stew meat, liquid campells stew seasoning, toss all of it in a slow cooker... turn it on (for extra laziness, use a slow cooker bag so you don't have to clean it after).
At dinner, spoon it into bowls (or if I feel fancy and like putting some effort in, hollow out some bread bowls), eat.
Then the next day throw it in the microwave for two minutes, eat it again for lunch. Do it again for dinner. Cumulative work is about 10 minutes for three meals, and the only dishes are your bowls and spoons (if you used a slow cooker bag).
