Oh man Quin xD I had a similar setup when I lived in my closet-sized guest house in California. I had a microwave, a toaster oven, and a waffle iron I turned into a grill xD

I've never used hot plate. I'm under the impression that you use a pan to cook on it, is that right? If so, you should be able to cook a number of things that you would be able to cook on a stovetop. If not... is there a way you can acquire an electric skillet? (I have no idea what is available in china or how remote you are!) They are relatively cheap in America.

If you can find a toaster oven, I would also invest in one, and they can also be relatively cheap. My most common meal was a fillet of salmon with chopped summer squash and slices of red onions. Bake in that tiny thing for 40 minutes and you're good to go.
