I used to have one of those in when i lived in a travel trailer, you can pretty much cook anything you can fry with time and the right amounts.
Fish sounds good, you can bread it, heat some olive oil in the skillet, and fry it up lol. I don't really like the microwave cause everything seems to come out mushy as far as bake-able foods go. ah, hambergesa!! hamburgers could be done in it too, you just reminded me of the good ole campfire, get some tin/aluminium foil, wrap corn on the cop/potatoes have some baked potatoes/corn on the cob lol. If you can find a grate you can grill on it just let the fire burn down to embers no flames. Anywho, some grilled cheeses lol, fried okra, even vegies, also the microwave is good for those like a can or bag of frozen green-beans or something. There is plenty to do with a skillet and a microwave you just gotta check it out, you can even buy that chinese food in a box from the frozen aisle and cook that up in it, check the back for directions. yep, and much more.
