Add chicken thighs to a mixing bowl.
Add 2 TBSP coconut aminos, salt, and garlic. Mix and set aside.
While chicken marinates, prep all the vegetables.
Heat a large skillet on medium heat.
Add 2 TBSP olive oil. Once hot add carrots and cook for 3 minutes, stirring occasionally.
Then add in bell peppers and Bok choy and stir to combine. Cook for 2 minutes.
Remove vegetables to a bowl.
Add remaining 2 TBSP olive oil. Once heated add green onions and sauté until the white parts are translucent (1 minute) stirring occasionally to avoid burning.
Increase heat to medium high then add chicken including leftover marinade. Cook chicken for 5 minutes stirring occasionally.
Reduce heat to medium and add remaining 1 TBSP of coconut aminos then stir to combine.
Mix together the water and tapioca flour to form a slurry. Pour the mixture in to the skillet and immediately stir to combine. The sauce should thicken after a minute or 2.
Once sauce is thickened, add in vegetables and mix for a minute. Turn off the heat.
Once all the vegetables are coated in the sauce, taste for additional seasoning then you're ready to serve.
