Whenever there are leftovers I usually just toss them in a food storage container and pop it into the refrigerator. Then if I want to reheat them for another dinner (ahem...leftover night) or for lunch I just reheat in the microwave or on the stove-top. If the noodles seem dry I might sprinkle on a little water to moisten everything up. u003cbr/u003eu003cbr/u003eIf you have a lot of leftover goulash you could also go ahead and make a casserole. Just put the goulash in a oven-safe/freezer safe casserole dish, sprinkle on some shredded cheese over the top and add a lid or cover in aluminum foil. Pop that casserole into the freezer for up to 3 months. Reheat in the oven for about 45 to hour at 350u003cstrongu003e°u003c/strongu003e F or until warmed through and the cheese is melted. And voila you have a whole new dinner!
