Heat avocado oil in a large pot over medium-high heat. Add chicken and cook for 5–7 minutes, or until cooked through. Remove and set aside.
Add bell pepper and carrots to the same pot. Sauté for 3–4 minutes. Add garlic and ginger and cook for another 30 seconds.
Add chicken broth, coconut milk, peanut butter, coconut aminos, lime juice, honey or maple syrup, and sriracha. Whisk until smooth and bring to a gentle simmer.
Add ramen noodles and cook according to package directions, approximately 4–6 minutes, stirring occasionally. Add extra broth if needed.
Return the chicken to the pot and add spinach. Cook for another 1–2 minutes, until the spinach wilts and the chicken is heated through.
Divide among four bowls and garnish with your favorite toppings. Serve immediately.
