I have one of those gas stoves/ovens, and i found a grill that sits like a pan on the stove. It is great. No matter the weather, or the amount of food i am cooking, it is easy and fast to use, and to clean. (is has a pot type for the bottom part, you put water here, and there is a large hole in the middle-not sure how that helps out!, the top half is the grill, which is like a pan, only it has holes all around. the water heats up and the steam heats up the pan and voila!) I only hope when i move that the pan can be used on the regular stoves!!!
I also use plastic bags almost all the time in the fridge or disposable tubberware. that way if food goes to long in the fridge i dont have to clean a nasty bowl-or waste my good bowls holding fridge food-and the plastic bags makes more room in the fridge-especially since i prepack all my meals for work.
