China does do stuffed peppers. They look like this and there is nothing wrong with them. I eat them often.
They don't look anything like my dinner tonight, though - nor what Chinese friends would think of in terms of stuffed peppers. What I made tonight had Chinese elements, but...
Red and yellow bell peppers stuffed with a mix of hachéed pork marinated in garlic, ginger, chilli and Shaoxing wine. Stir fried with a splash of soy sauce, I had some flowering chive stems leftover (minus flowering ends) so they went in, too. Stuffed into the peppers and into the oven for about 25 mins.
Stir-fried mushrooms with scallions. Matsutake, cèpes and shiitake.
Coriander/cilantro rice.
