Cook rice noodles according to the package instructions. When draining, reserve 2 tablespoons (or more depending on your preference) of pasta water.
Make the sauce by mixing together the peanut butter, coconut aminos, lime juice, garlic, ginger, red pepper flakes, and salt and pepper until smooth. Adjust according to taste.
When the water is almost boiling start the shrimp. Heat a large saute pan over medium-low heat. Add 1/2 tablespoon oil and let it get hot, about 30 seconds. Add minced garlic and saute for 30 seconds until fragrant. Add shrimp, season with salt and pepper, and saute for 3-5 minutes, flipping once halfway through, until practically cooked through. Remove from the pan. They will go back in the pan, but you don’t want to overcook later on.
Add the remaining 1/2 tablespoon of oil. Add broccoli and saute for 3-4 minutes, stirring occasionally. Add peppers and salt and pepper and saute for another 5-6 minutes, stirring occasionally.
Drain and rise rice noodles, saving at least 2 tablespoons of the pasta water. Turn down the heat to low and add noodles, shrimp, sauce, and pasta water into the pan with the veggies. Stir until combined and warmed through (careful not to overcook shrimp). If needed, add more pasta water to thin out the sauce.
Top with optional toppings and enjoy!
