Cook the noodles. Soak the rice noodles according to the package instructions. They should be al dente. Drain and rinse under cold water. Set aside.
Make the sauce. In a small bowl, whisk together the sauce ingredients until smooth.
Saute vegetables. Heat a large pan (12-inch is ideal) over medium-high heat. One hot, add 1-2 tablespoons of oil, shallot, garlic, carrot, bell pepper, and green onion. Cook for 1-2 minutes stirring frequently.
Cook the chicken. Add 1 tablespoon of oil if needed and the thinly sliced chicken or protein of choice. Cook stirring often until the chicken is starting to turn white but not completely cooked through. Stir in 1 tablespoon of the pad thai sauce.
Scramble eggs. Push vegetables and chicken to one side of the pan, pour in beaten eggs on the other side, and scramble until just set.
Combine. Add the tofu, bean sprouts, cooked noodles, and sauce. Toss to combine and turn off the heat.
Garnish. Garnish with chopped peanuts and lime wedges. Serve immediately.
