When I'm too lazy to make anything else, I fall back on quesadillas. Tortillas = carbs, cheese and maybe beans = protein, and spinach or sprouts or avocado or tomatoes = the veg/fruit. Complete meal in five minutes! Can add sour cream and spices and various sauce stuff for extra flavor variations. And if I'm REALLY lazy, they can even be made in the broiler without dirtying a frying pan. Or I guess if you have a toaster oven (I don't) they could be popped straight in there, too.

The depths of my laziness get pretty low, sometimes.
