Tomatoes can be used to make yellow duck fish (that's what people in Hunan and Hubei call it, I don't know what your fish is called). It is delicious.
Fried rice with diced cucumber and ham, with pickled pepper, is fragrant and slightly sour, and delicious.
Spinach salad is mixed with Chili oil like Laoganma. I don't know if you've tried. Very delicious.
