Preheat oven to 350 F. Trim the stem ends from the eggplants and slice the eggplants in half lengthwise. Scoop out the inside to create a shell with about 3/4 inch of flesh remaining on the eggplant skin. (Reserve scooped-out flesh for soup, stews, or stir-fries.) Heat oil in a large saut pan or skillet and saut onion with garlic and ginger for 2 minutes. Add bell pepper and saut for 2 minutes. Add mushrooms, parsley flakes, red miso paste, soy sauce, and vinegar, and saut for an additional 2 minutes, stirring well to distribute ingredients. Fold in cooked quinoa, kidney beans, and sesame seeds and stir well. Fill eggplant shells with quinoa filling, heaping it on top.
Place in a baking dish with 1 tablespoon water on the bottom of the dish. Bake uncovered for about 40 minutes, until filling is golden and eggplant is tender.
