I've also found having cooked pasta in the fridge terribly handy for packed lunches. You can quickly mix up a single serving of pasta with salad dressing, or some frozen veggies and diced cold cuts, or make a quick homemade mac & cheese by whipping up a cream sauce in a skillet with a bit of cream and shredded cheese.

shredded (or cubed) cheese (consider Parmesan)
diced or finely sliced cold cuts (salami & ham are favorites)

halved grape tomtoes
fresh herbs such as basil
