I had a throwback from high school hot lunch days - creamed peas with a canned tuna drained, and mixed in. All that was missing was the noodles. I used fresh, sweet peas for better flavor. Add yellow squash boats with butter, and fresh basil, and steamed broccoli, and that's a filling, if somewhat unimaginative meal. I used to like the mushroom soup/corned beef hash, noodle mixture better.
I won't go into how good the hot lunch program was in my home town, back in the 60's, and 70's. Everything was freshly made on site, with real, fresh food. And as I was not a picky eater, and loved most everything, I often was given extra cheese, or fish sticks, or whatever that other kids didn't care for.
