This doesn't need to be an all-day cookfest that swallows your Sunday- take 1 hour, pop some chicken breasts in the oven, chop and/or saute some veggies, and wrap everything into tupperware.
When hunger strikes, reach into the fridge, take 3 minutes to assemble, and there you go- waistline-friendly and time-friendly too.
