Optional (but recommended): Brine chicken breasts for 5-12 hours. Get recipe/instructions here. Pre-heat oven to 400 degrees. Cut spaghetti squash in half and scoop out seeds. Rub cut sides with 1 tsp olive oil and season with 1/2 tsp lemon pepper seasoning. Bake for 35-40 minutes until flesh flakes away easily with a fork.
Heat remaining olive oil in a large skillet over medium-high heat. Season chicken breast on both sides with salt, pepper, and 1/2 tsp lemon pepper seasoning, then add to skillet and brown on each side for 1-2 minutes, then set chicken aside.
Add butter to skillet until melted and hot, then add onion and garlic and sauté until tender. Stir in flour until it is absorbed, then gradually whisk in wine, chicken broth, and coconut milk.
Add sun dried tomatoes and remaining spices to skillet. Stir well, then add cannelini beans to the skillet and stir to combine. Return chicken to skillet and spoon sauce over chicken. Lower heat to a simmer for 10-15 minutes until chicken is cooked through. Stir the kale in during the last 5-10 minutes of cooking, then remove from heat.
Remove chicken from skillet and allow to rest for a few minutes before slicing. While the chicken rests, add spaghetti squash to skillet and stir until well combined and heated through.
Divide into 5 servings and add sliced chicken on top. Top with parmesan cheese before serving, if desired.
