In a large pot, heat coconut oil over medium heat. Add the garlic and ginger and sauté for 1 minute until fragrant.
Stir in the sliced bell pepper and red curry paste. Cook for another 2-3 minutes to bring out the curry flavors.
Pour in the coconut milk and broth. Stir in the fish sauce and coconut sugar. Bring the soup to a gentle simmer.
Add the rice noodles directly to the pot. Let them cook according to package instructions (usually about 4-5 minutes), stirring occasionally to prevent sticking.
Once the noodles are nearly cooked, stir in the shrimp and spinach. Cook for another 3-4 minutes
Protein swap: Try adding chicken, tofu, or even scallops instead of shrimp.
Extra veggies: Mushrooms, carrots, or snap peas would be delicious additions!
