The best thing to do on a rainy, lazy Sunday, is veg on the couch with a good book or a good, favourite movie. Napping in the afternoon is nice, too.
There is Lazy Sunday food, too. For lunch, Mum's rice and tomato soup is best, with grilled cheese or tuna melt sandwiches. For supper, breakfast food for dinner is awesome, as is meatloaf and fried potatoes, or Shepherd's pie. Sunday is definitely the time for comfort food.
