In a mixing bowl, combine creamy peanut butter, soy sauce, freshly grated ginger, minced garlic, lime juice, and Sriracha. Whisk until smooth and creamy.

Heat a large skillet over medium heat, add oil, and cook diced chicken breasts until golden brown and cooked through, about 7-10 minutes.

Pour the prepared peanut sauce over the cooked chicken, reduce heat to low, and simmer for about 5-7 minutes.

Remove from heat and serve over steamed rice, noodles, or lettuce wraps, garnished with chopped peanuts or sliced green onions.
