Heat a large skillet or wok over medium-high heat and add 2 tablespoons of oil. Add in the chopped green onions and minced garlic and sauté for about 2-3 minutes until fragrant.

Reduce heat to medium and add the cooked rice noodles, gently stirring to combine. Heat through for about 1-2 minutes.

In a small bowl, whisk together the peanut butter, soy sauce, and sriracha. Pour over the heated noodles and stir well until coated.

Taste and adjust seasoning as needed; serve hot, optionally garnished with additional green onions or vegetables.
