Preheat oven to 375F
Arrange the meatballs on a sheet pan, and bake until meatballs are cooked. 15-30 minutes depending on the size of meatball and if you use frozen or fresh meatballs.
While the meatballs bake, in a large pot, heat 2 tablespoons of the coconut cream from one of the two cans of coconut milk.
When the coconut cream is heated, add the red curry paste to the pan and saute until the coconut cream and curry paste are combined (3 ish minutes).
Pour all the remaining coconut milk from the two cans to the pot.
Add in the lime juice, sugar and fish sauce, allow to simmer (covered) on low/medium heat, until the meatballs are cooked.
Once the meatballs are cooked, transfer them to the pot.
Add in the peppers, and spinach. Turn heat up to medium.
Simmer until the spinach is wilted and bell pepper is desired doneness.
Remove the meatball and sauce mixture from the heat. Stir in the cilantro and basil.
Serve with rice or noodles of choice.
