How to Make It
Trim the ends of the bok choy. Wash, pat dry with paper towels, and then set aside.
Heat a large skillet or wok over medium-high heat. Add oil, and then stir in the shallots and garlic. Cook for about 1 minute, or until soft.
Stir in the peanut butter, water, fish sauce, rice vinegar and brown sugar. Stir sauce until well combined and simmer on low heat for about 30 seconds, or until the sauce thickens.
Increase heat to medium-high heat, and then stir in the bok choy. Cook for 1-2 minutes, or until the bok choy is tender and just wilted.
Garnish with the roasted peanuts and serve warm.
