Our family used to eat a lot of stir-fry a number of years ago and then got out of doing that for a while. We've rediscovered stir-fry, now that I know about San-J Wheat-Free (and also gluten-free) Tamari. I can make my own Teriyaki sauce at home and use that with our meat and veggies and then serve it over rice.
1/4 cup San-J Wheat-Free Tamari
1/4 cup vegetable or olive oil
2 TBSP ketchup (Heinz is gluten-free)
1 TBSP white vinegar
1/4 tsp pepper
2 cloves garlic, crushed
Mix all ingredients right before serving as the ingredients tend to separate if you mix and then leave them to sit.
