Leftover are really great. I don't own a microwave, and so always reheat things in the oven or on the stovetop. It's so easy, your leftovers don't dry out, and they get just as crispy and delicious as they were originally! No squishy microwave dinners here.
For the tapas leftovers I reheated the Spanish Tortialla in the oven at 350° in the CorningWare dish that I had it refrigerated in. Those dishes are really durable and practical. My aunt gave me some when I was in University and they've lasted beautifully.
I reheated the mushroom loaf and white beans and mushroom on the stovetop.
For a side I threw together a quick salad of mixed greens, red pepper and tomato, with a balsamic vinaigrette.
Total time: 15 minutes.
