Here's mine:

1 head of cabbage, cored and chopped
1 stick of butter
1 large white onion, sliced

Melt the entire stick of butter in a large skillet over medium heat, add onions and cook until carmelized. Add cabbage a little at a time until it wilts, and cook for 20 min. over medium low heat, covered.

Eat. Lots of it. Leftovers are good too, reheat in the microwave or over a double boiler. Cabbage is great for gut flora.

Slovak depression recipe from great grandmother, except she added noodles or potatoes to it. I have found that it tastes the same without them.

Forgot to mention that. I ALWAYS go full-fat.

Edit to add: that sounds freaking delicious! (but I'm a cabbage fiend)

a couple of years ago when I was in full baking mode I experimented with replacing most of the flour with chopped cauliflower.

It worked and made good bread, but I can't find my notes and haven't had time to redo the experiments.

Anyone is free to play with the idea since I won't get around to it again soon. Squashes, and other such stuff worked, too, but not so low carb.
