To cook veggies, heat a deep pan over medium-high to high heat. Add oil to the pan—and be sure to use an oil with a higher smoke point, like avocado oil or light olive oil, since we’re cooking over high heat.
Add chopped sweet potato (or butternut squash), along with half of a lemon. Cover and allow to cook for 3 minutes.
Once browning on the bottom, uncover and season to taste with coconut aminos and salt. Turn heat down to medium-low, cover, and continue to cook for 5-7 minutes. (Now is a great time to start cooking your blackened salmon!)
Once cooked through, remove sweet potato from pan and set aside.
Add a drizzle of oil to warm pan and saute garlic for one minute. Once fragrant, add spinach and a pinch of salt. Cover and allow to wilt for 1-2 minutes.
Serve cooked sweet potato and spinach on a plate with blackened salmon! Squeeze juice from blackened lemon onto salmon and enjoy.
