Just marinate the spare ribs and vegetables and bake in the oven. It's great if you grill it with vegetables cut to various sizes.
Grilling heartily cut vegetables in the oven is delicious. You can use various kinds of meat, but the fat that renders from the spare ribs is delicious and I think it goes well with the vegetables.
Make sure to flip the meat over once while baking in the oven.
Enjoy Japanese food around the world.
