Cook brown rice or quinoa as per package instructions. Prep and chop all veggies and meat. Stir fry happens fast.
In a medium bowl, add soy sauce, maple syrup, rice vinegar, toasted sesame oil and cornstarch. Whisk until combined and set aside.
Preheat large cast iron skillet (the best for char!) or deep skillet on medium-high heat and swirl 1 tbsp of oil to coat. Add cauliflower and cook for 5 minutes, stirring just a few times to allow char develop. It should be cooked al dente and not mushy. Transfer to medium bowl and set aside.
Return skillet to the stove and swirl remaining 1 tbsp of oil. Add chicken, garlic and ginger; cook for 7 minutes, stirring just a few times to allow char develop.
Give teriyaki sauce a whisk, pour over chicken, stir and cook for 1 minute or until thickened. Add previously cooked cauliflower, stir and let simmer for 1 more minute, continuing to stir to coat veggies and meat in sauce. Turn off heat.
Sprinkle with green onion and sesame seeds. Serve hot with brown rice or quinoa.
Notes
Store: Refrigerate in an airtight container for up to 3-4 days.
Freeze: In an airtight container for up to 3 months. Thaw in the fridge overnight. Reheat in a pot with a splash of water or broth, simmering on low while covered. Stir a few times.
Skillet: I enjoy using a well-seasoned cast iron skillet for this recipe because it gives cauliflower an unbelievable charred flavor. You can also use large deep non-stick skillet or wok. Just keep in mind wok will "steam" veggies more than char, unless you have a very good wok that sears well.
Toasted sesame oil: Adds a nice smoky touch to teriyaki sauce but you can skip if you don't have any on hand.
