We have a couple solutions. We have about 3 of the plastic divided compartment trays like you used to get school lunches on. My daughter loves those since she doesn't want her food touching even though I told her it slams into each other once she swallows it ;-)
We have about 4 porcelin covered steel plates that I bought from cabella's years ago that we use often as they are easy to clean. They have a 1" lip around the edge so are kind of a deep dish plate. Great for stews, chili, etc. but also fine for normal plate fare.
Then we also have some 10" plastic plates, also loved for their ease of cleaning. And of course paper plates for the quick snacks, sandwich and chips meals.
Never felt the need to have heavier home style plates while camping. The ones above are plenty sturdy and easy to clean and store. And Lighter.
