Incredibly simple and delicious! I shredded my zucchini instead of dicing it, used up some leftover shallots and added white beans and mushrooms. I think the mushroom really sent it over the top. Could work with other veggies too: peas, carrots, spinach, broccoli/cauliflower if you steamed it a bit first.
UPDATE: I used 3 medium-large zucchini plus one small package of mushrooms, and while the pan was a bit crowded it still turned out really good. Also the 3 additional tablespoons of butter don’t seem to add much when there’s already 1 tablespoon and sheavy cream.
