Step 1

Whisk peanut butter, soy sauce, water, Sriracha, lime juice, ginger, and garlic together for sauce and set aside so flavors can mix.

Step 2

Heat oil in a large, nonstick saute pan over medium-high heat. Sear the bok choy, cut-sides down, until they are starting to brown, 3 to 4 minutes. Flip them over and continue to cook until browned, 2 to 3 minutes more. Season with salt and pepper.

Step 3

Place bok choy on a plate. Drizzle with the sauce and sprinkle with peanuts and cilantro.
