We like both Smitten Kitchen's Pizza Beans, and Smitten Kitchen's brisket chickpeas (not sure that's the name). I have this need to serve something green so I usually add some kind of bagged salad to both.
Lentil/vegetable soup is another thing I make that always disappears, but I don't use a recipe, and I usually serve it with grilled cheese so I'm not sure that counts as "one dish".
Egg roll in a bowl

Fried rice -- I start with riced cauliflower (the raw kind, not the frozen) and toast it, and then onions, add brown rice, soy sauce, frozen mixed veggies, and several eggs. Could add edamame if you're vegan and don't want eggs.
