In the last few months I lived in Austin, I made a concerted effort to use as much of my pantry and frozen stuff without going to the grocery. Some experimentation occurred, some with good results, including something I call 4 Can Cassarole.
It was 1 can of green beans, 1 of diced tomatoes, one of cream of mushroom soup, and 1 can of peeled potatoes* (all with liquid included), dumped into a casserole dish and tossed into an oven for a while. I had seasoned it with things like pepper, powdered garlic and onion flakes.
* I usually buy fresh potatoes, and don’t recall how I came to possess 2 cans of potatoes. When I make this dish currently, I use fresh potatoes- typically baby Yukons- so now I guess it’s technically 3 Can Cassarole.
