Leftovers can be stored in the fridge for 3-4 days. You can also portion out the cashew chicken with rice into containers for a desk lunch or meal prep.
For a non-soy option, I recommend using a No-Soy Sauce. Then adding a sweetener like Honey. If you are gluten-free, then you probably know that most soy sauces contain wheat flour. The No-Soy sauce, Liquid Aminos, and Coconut Aminos are all great Gluten-Free options. Just be sure to check the labels.
For a low sodium option, I recommend using a low sodium soy sauce, liquid aminos, or coconut aminos. Regular soy sauce and golden mountain sauce will have almost double the sodium content.
