MAKE THE SAUCE: In a medium bowl, whisk together sauce ingredients until completely combined - 1/3 cup Swerve brown sugar, 1/4 cup fish sauce, 2 Tbsp tamarind concentrate, 2 Tbsp light soy sauce. Set aside until ready to use.
COOK THE NOODLES: Cook the noodles al dente according to package instructions. Drain the noodles in a strainer, then rinse with cold water briefly to halt their cooking. Spritz lightly with olive oil cooking spray to prevent the noodles from sticking.
COOK THE CHICKEN: Meanwhile, heat a large sauté pan or wok over high heat and spray with cooking spray. Add the 1 lb cubed chicken and sauté for 3-5 minutes, tossing occasionally, until the chicken is cooked through. Use a slotted spoon to transfer the chicken to a clean plate and set aside.
COOK THE VEGGIES: Add cooking spray to the sauté pan, along with the 1 cup bean sprouts, 1/2 cup shredded carrots, and 4 cloves minced garlic. Sauté for 2 minutes, stirring occasionally.
COOK THE EGGS: Push the veggies to one side of the pan and add the 3 whisked eggs on the other side. Cook the eggs until scrambled, stirring often.
PUT IT ALL TOGETHER: Now add everything back in with the eggs and veggies — the cooked noodles, cooked chicken, sauce, and 3 green onions sliced in 1-inch pieces. Give the mixture a good toss until everything is evenly coated in the sauce. Let it cook in the skillet until the rice noodles absorb some of the sauce. Remove pan from heat.
SERVE: Serve sprinkled with lots of crushed peanuts, extra crushed red pepper flakes (if desired), and a good squeeze of fresh lime juice. Enjoy!
