Marinate the turkey
Chop your mushrooms and season them with a dash of salt.
Prepare your fresh toppings. Chop and cube your cucumber, watermelon, and green onion. Shred your carrots.
Next, chop your herbs that will also serve as toppings. These are your basil, spearmint, and cilantro.
Prepare the turkey. Add a tablespoon of cooking oil to a wok and heat. As your oil is heating, strain your turkey, leaving the leftover marinade in the bowl - when we cook it down this will become our topping sauce. When your oil is sizzling, add the turkey chunks. Cook until they are browned and juicy.
Place your rice noodles in a ceramic bowl and boil a kettle full of water. When your water is boiled, pour over your rice noodles and let sit for 10 minutes.
Pour your leftover marinade into a medium saucepan and heat.
Simmer until you see your sauce start to brown and thicken - this should take about 10 to 15 minutes. Remove the sauce from heat, and strain into a medium bowl.
