Cook the stew meat on medium-high heat for about 10 minutes, or until cooked (a little pink in the middle is fine.)
While meat is cooking, spiralize 2 zucchinis. (You can try squeezing excess water out of the zucchini before cooking. Use a cheesecloth or paper towels)
When the meat is done cooking, scoop meat aside on a plate or bowl and add the spiralized zucchinis to the same pan you cooked the meat in.
Cook zucchinis on medium heat for about 3 minutes, tossing frequently.
Once zucchini noodles are cooked, turn off heat and add stew meat back to pan with ¼ cup gluten free (low sodium) soy sauce, more if desired. Sprinkle on 2 tablespoons sesame seeds and enjoy!
