Season both sides of chicken with salt, pepper, paprika and thyme. Heat olive and coconut oils in a large skillet over medium-high heat until oil is shimmering. Carefully place chicken thighs in skillet and cook 5-6 minutes per side, depending on the thickness, or until chicken is browned and firm. Transfer to a plate.
Clean out your pan if it has any burnt residue, then return to medium heat. You should still have some leftover oil in the pan, and browned bits will add a lot of flavor to your sauce. But if it is very dry, add another tablespoonful or so of oil.
When hot, add onion. Sauté until soft, stirring occasionally, for 6-8 minutes. If the onion looks like it will stick, deglaze the pan with a little water and stir up the brown bits. Add garlic and cook, stirring constantly until fragrant, about 30-60 seconds.
Pour in the coconut cream; stir well and bring to a simmer. Add the spinach and tomatoes and simmer for about 5 minutes, then stir in artichoke hearts, lemon juice and nutritional yeast. Simmer until flavors are well combined and the sauce has slightly thickened, about 5 minutes. Add the chicken and simmer until it is done, about another 10 minutes.
Test chicken for doneness. Taste and adjust seasonings, as this is a fairly low-salt version. You may wish to add more lemon juice instead, which brings out salty flavors.
Serve over spaghetti squash, or pasta of choice.
