Mustard spinach + Yellow zucchini

Komatsuna or Japanese mustard spinach (Brassica rapa var. perviridis) is a leaf vegetable. It is a variety of Brassica rapa, the plant species that yields the turnip, mizuna, napa cabbage, and rapini. It is grown commercially in Japan and Taiwan. The name komatsuna is from the Japanese komatsuna, "small pine tree greens". It is stir-fried, pickled, boiled, and added to soups or used fresh in salads. It is an excellent source of calcium.

Zucchini or courgette is a summer squash which can reach nearly a meter in length, but which is usually harvested at half that size or less. Along with certain other squashes and pumpkins, it belongs to the species <i>Cucurbita pepo</i>. (Wikipedia) Yellow zucchini, or golden zucchini, was developed by the W. Atlee Burpee Seed Company from a Fordhook Zucchini crossed with a Bicolored Gourd and released in 1973 (http://www.cooksinfo.com/burpee-golden-zucchini). It is said to have a distinctive flavour that is somewhat sweeter than green zucchini.
