The only thing difference about this tenderloin cook last night from normal was the fact that I used Water Spinach. Other than that, I used Paul Prudhommes Pork Magic and made beans. After looking into Water Spinach it has some interesting applications and in Florida it is even considered an invasive grass species...interesting.

Ipomoea aquatica is most commonly grown in East and Southeast Asia. Because it flourishes naturally in waterways and requires little if any care, it is used extensively in Malay and Chinese cuisine, especially in rural or kampung (village) areas. It has also been introduced to the United States where its high growth rate has caused it to become an environmental problem, especially in Florida and Texas. It has been officially designated by the USDA as a "noxious weed" (the term "noxious" refers to its effect on the environment, not to any toxicity.
The vegetable is a common ingredient in Southeast Asian dishes. In Singapore, Indonesia and Malaysia, the leaves are usually stir fried with chile pepper, garlic, ginger, dried shrimp paste (belacan/terasi) and other spices. In Penang and Ipoh, it is cooked with cuttlefish and a sweet and spicy sauce. During the Japanese Occupation of Singapore in World War II, the vegetable grew remarkably well and easily in many areas, and become a popular wartime crop.
In Chinese cuisine (Chinese: 空心菜; literally "hollow vegetable") there are numerous ways of preparation, but a simple and quick stir-fry either plain or with minced garlic is probably the most common. In Cantonese, the water spinach is known as 蕹菜 (Jyutping: ung3 coi3, sometimes transliterated as ong choy). In Cantonese cuisine, a popular variation adds fermented bean curd. In Hakka cuisine, yellow bean paste is added, sometimes along with fried shallots. The vegetable is also extremely popular in Taiwan, where it grows well.
