Boil a large pot of water. Cook rice noodles until just tender, then drain and rinse to stop cooking.
Whisk peanut butter, soy sauce, lime juice, rice vinegar, brown sugar, sesame oil, chili-garlic sauce, ginger, garlic, and warm water until smooth.
Warm the oil in a large skillet over medium heat. Sauté carrots and bell pepper until crisp-tender, 2–3 minutes.
Add noodles to the skillet. Pour in the peanut sauce and toss until evenly coated and heated through, 1–2 minutes.
Plate the noodles and finish with scallions, cilantro, and chopped peanuts. Adjust with a splash of water if too thick.
Notes
Variation: Add sautéed tofu, shredded rotisserie chicken, or steamed edamame for extra protein. Swap almond butter for a different nutty flavor. For a chilled noodle salad, rinse noodles well, cool completely, and thin the sauce with a bit more water. Leftovers keep in an airtight container up to 3 days; loosen with warm water before serving.This recipe is an original creation inspired by classic Quick Peanut Sauce Rice Noodles flavors.
