Season both sides of chicken with salt and pepper.
Heat a large skillet to medium high heat.
Add avocado oil to the pan and then chicken breast. Sear chicken for 4-5 minutes per side.
Remove from pan and set aside.
Then immediately add butter to the pan and let melt. Add in garlic and saute for 30 seconds, stirring the entire time.
Add in onions and saute until translucent, about 2 minutes.
Deglaze the pan with white wine, scrapping with a wooden spoon to get any brown bits from the bottom. Season with salt and 1/8 teaspoon of red pepper flakes.
Add in cherry tomatoes and cook for 3-4 minutes. As the cherry tomatoes start to soften, press down on them with a spoon to make them burst.
Next add in spinach and saute until wilted down, about 2 minutes.
Pour in the coconut milk. Stir and simmer for 3-4 minutes.
Then add lemon juice and fresh basil. Stir to combine.
