I made something loosely based on what Jinx made.

My shopping trip got me 2 pounds of ground beef that expired today. I
browned that up, put some in the freezer in small portions and the rest =in
a casserole dish. I add three bags of frozen veggies. I got things a while
back on clearance somewhere. Red potatoes, pea pods and red peppers in some
kind of sauce with herbs. Seemed not to be much sauce. To this I add three
carrots and three celery ribs that I sliced and cooked briefly in the
microwave. Also dried onion, parsley and black pepper. A can of cream of
mushroom soup and another of cream of celery. Plus some water to thin it
down. Baked uncovered until heated through. I debated adding cheese but
decided not to as it sounded weird with the pea pods.

As it turned out, we had an unexpected guest for dinner so I was glad that I
had plenty. Was a little worried that it might not be super tasty, but it
actually was quite good. If I make something like this again, I will add
fresh onions and more of them.
