Cook your pasta according to package instructions.
Cook your chicken anyway you like. I used chicken tenders grilled with lemon pepper seasoning because that's what I had on hand. You could also use shredded chicken or pan-fry you diced chicken in a cast iron skillet with a little coconut oil.
Melt coconut oil in large skillet over medium-high heat. Add onion and cook until translucent. Then add the garlic and cooked chicken.
Let your garlic cook for about 30 seconds. Then add tomato sauce, salt and pepper, basil, and parsley to your skillet. Stir to combine.
A note on tomato sauce: You can use whatever tomato sauce you like! You can used canned tomato sauce, jarred spaghetti sauce, homemade spaghetti sauce, etc. It's really up to you. If you do use a plain tomato sauce, you'll want to adjust your seasonings a bit to compensate. Just do some taste-testing as you cook.
Bring the sauce to a simmer. You can let your sauce simmer for 15-20 minutes to let the flavors develop, or you can move right into the next step. I let mine simmer when I have time.
Add coconut milk to your sauce and stir well. Let it heat for a few minutes and then remove from heat.
Combine pasta and sauce into a pot. Serve hot with a garnish of grated Parmesan cheese (optional) and a little parsley (optional).
