for vegetables try garlic chives, water spinach, bok choy, napa cabbage, tofu skin, or lotus root.
for preserved shit try chili bamboo shoots, pork floss, or char siu sauce.
for random toppings try meat or fish balls, or dumplings.
or if you live in a shitty area like i do you could just forgo all that and stick with green onions, eggs, and sliced pork shoulder. and sriracha sauce too if you've given up on your taste buds.
