This dish was inspired by finding purple potatoes and papayas and Chinese cabbage (which is a softer less bitter cabbage) but if you can’t find these items here is a list of substitutes to still be able to make this dish: Instead of purple potatoes use: regular potatoes or sweet potatoes. Instead of Chinese cabbage use regular cabbage. Instead of asparagus use sugar snap peas or green beans. Instead of shallots: use regular onions . . .
