Notes on Ingredients
- Sweet Potato Noodles: Also known as glass noodles. You can use any noodles you’d like here including rice noodles or udon.
- Soy Sauce: Only 2 tablespoon are used in the sauce. If you want to keep this dish soy-free, replace the soy sauce with an additional 2 tablespoon of coconut aminos. Use gluten-free soy sauce if needed to make this recipe gluten-free.
- Kale: Any green works here including spinach.
- Tofu: Optional but adds a great source of protein in this dish. I love to make my Vegan Air-Fried Tofu Nuggets to put on top!

i accidentally got a small package of sweet potato noodles, so i mixed them with pad thai rice noodles to get to the acquired amount. I also added some plant based steak! This meal was so delicious and I cannot wait to eat it again!

I was SO excited to see this recipe! I’ve been eating the frozen meal of this from Trader Joe’s for a long time. And for years I’ve been saying, “I bet I could make this better at home!” It wasn’t until I saw how simple this recipe was that I got the confidence to make it at home. It’s an amazing meal prep, and I appreciated you linking the noodles in the recipe. My local grocery stores didn’t have any, but it was so easy to order. I added tofu to make it more filling and for protein. Highly recommend!
