Anything you can fix in an oven, you can do in an electric skillet or a Dutch Oven over a fire.
When we had no oven in the camper (previous camper), we learned how to bake cakes, cookies, roasts, stews, even pizza using an electric skillet with a lid. Baked potatoes were OK, but found frying them was much easier.
We tried using one of these, but found it was difficult to retain a steady temperature, especially outside. Any wind would cool the temperature so fast, but inside the camper on the stove top it worked pretty well. However, these get very hot, and inside the camper, the risk of bumping into it and getting a burn is pretty high. It's because of using one of these, we navigated to an electric skillet.
Coleman makes these, and they sell for $39.
