I am a northerner, and northerners basically don't put soy sauce in cooking. Vegetables that can be eaten raw can be eaten without soy sauce, as well as garlic moss, leeks, scrambled eggs with tomatoes, bitter gourd, zucchini, cauliflower, potatoes, beans, oil wheat vegetables and small vegetables. If you really can't help it, you can try to make some light soup, which is delicious and healthy. Give it a try!
