Most of the cooking we do when camping is on the grill. We use the oven mostly for pizza, biscuits/rolls and reheating leftovers. We don't really use the microwave much.
Outside we have a portable grill and a two burner Coleman stove. Since most of what we do is grilled, we needed separate grill and stove. Bacon is made on a griddle as are pancakes. For our summer trip this year, I'll probably be bringing the smoker as well.
Coleman makes a
2 Burner Grill Stove. It's a little pricey, but fits the bill. There are probably others out there as well.
