I would recommend a combination toaster and convection oven. While I have a regular oven in my small apartment, I rarely use it in favor of saving energy (and money on my energy bill) by using the toaster/convection oven. I have purchased toaster oven sized muffin tins (just a 6 muffin tin) and a toaster oven sized roasting rack that fits two sizes of meat. My oven came with a roasting pan. The convection features have done wonderful things for my pies. You can get them big enough to make pizza in. As long as you aren't cooking for a crowd, it will work wonders. Things I've successfully baked in there include:
- Cake (did have to do it one cake at a time for a layer cake)
- Pie (the convection feature is perfect for pie!)
- Steak (well, it was a broiled steak recipe - the best I can do without a grill)
- Chicken breasts
I had a friend who rented a place that has a convection cooking setting on the microwave. We successfully used it to make muffins once, but I haven't tried it further.
