Coat the eggplant and zucchini and carrot with olive oil, sprinkle them with a small pinch of kosher salt and roast them in the oven for 10-15 minutes. Start the egg boiling with a couple egg noodles if these aren't pre-cooked, likewise cook rice if there isn't any already cooked. Meanwhile, mix the cooked rice with ketchup (this makes it flesh-colored). Arrange the rice in the bottom of a small rectangular bento box, garnishing the outer rim with lettuce leaves and/or seaweed. Let the roasted eggplant and zucchini and carrot cool, then arrange them in two vertical rows to represent the outer labia. They should be wider apart at the bottom and closer at the top. Arrange the pickled ginger along the center between the two rows of roasted veggies. Place 1/2 of a boiled egg at the wider end of the veggies suggestive of a vaginal opening and one kidney bean suggestive of a clit at the top, surrounded by the two egg noodles to represent the hood.
