Heat the coconut oil in a large skillet with a fairly high rim over medium heat. Add the onions, ginger and a pinch of salt and saute for 3-4 minutes until the onions are fragrant and slightly softened.
Next, add the chicken and curry paste; saute for 5 minutes or until chicken pieces are cooked. Add the potatoes, carrots and garlic; stir to coat. Saute for 1 minute.
Add the coconut milk, coconut sugar, tamari, turmeric, red pepper flakes and salt. Stir to combine, Bring to a simmer and reduce heat to medium low. We want a simmer, not a boil. :)
Cook for 20 minutes to incorporate all the flavors. Then start tasting and adjusting flavors. Coconut sugar for sweetness, tamari or salt for saltiness and turmeric for earthiness. If you want more spice and intense curry flavor, add in some more curry paste. Don't be shy with these! This should be very flavorful. I usually add 1 more teaspoon of turmeric, 1-2 teaspoons of curry paste and a little more salt.
Add cashews and simmer for 2-3 minutes.
Serve over rice, quinoa or with naan. (Trader Joe's has great frozen packages of naan)
