Potatoes and tomatoes. For the UNIX-y among us, this could be called [Pot,Tom]ato Casserole. The literal-minded might prefer a simple Potato-Tomato Casserole. (Or Tomato-Potato. Let's call the whole thing off.)
In any case, the match-up might sound strange at first, but upon consideration, the two get mixed up with some regularity. Gnocchi can have a tomato sauce. French fries are often dipped in ketchup. Tomato usually seems to play the supporting role, though - a sauce or condiment acting as second fiddle to potato's leading man. Not so here! They share the stage, in a virtual buddy-picture of a casserole - or have I stretched the metaphor too far?
With the veg sliced, begin the layering in your casserole dish of preference. Potato, then onion, then tomato. Finish with a layer of potato. Put a little salt and pepper on each onion layer. Sprinkle oregano on each tomato layer. I use a fairly small and deep dish, so I got five layers of potatoes and four layers of everything else. I find that giving the whole thing a good press in the center after each potato layer will both even things out and also give a little compression to help it all hold together. Otherwise it tends to bulge in the center.
Gently add the cream, cover and place in a 350F oven for 45 minutes. While it cooks, cut some slices of mozarella to your preferred thickness. After forty-five minutes, check the casserole to see if it's done - a knive should slide easily through the potatoes. If it is, top with the mozarella and slide under a low broiler for a few minutes to melt and brown the cheese - keep an eye on it, though, since the difference between brown and delicious and black and less so can be a matter of seconds.
