The restaurant inspired hot veggie katsu curry sandwich Our hot katsu veg big'bao makes a delicious & convenient lunch, supper, or snack. Pop it in the microwave & watch the box fill with steam, creating a hot fluffy bao in seconds... ping! We mix our signature katsu curry sauce with chunks of sweet potato, black beans, red miso & fresh parsley, all beautifully wrapped in soft bao bread, ready to enjoy. Steam triggers the yeast in the dough, which creates a soft cloud-like texture. Enjoy a big'bao on its own, with vegetables/fries for lunch, supper or as a convenient snack.
