That casserole dish has just one tiny serving left, so you scrape it down the disposal. Stop -- it may not be enough for lunch tomorrow, but FitSugar says leftovers make an ideal snack, no granola required.

Split your leftovers into 200-calorie portions for right-sized snacks to keep your energy steady. You can grab a granola bar any day, try reheating a bowl of soup instead. Pyrex offers these durable glass bowls with plastic lids, so you can microwave those leftovers in glass, not plastic.
