Whisk together sauce ingredients: coconut milk, peanut butter, red curry paste, fish sauce, lime juice, brown sugar, garlic, chicken stock, ground ginger, and crushed red pepper flakes directly in the crockpot.
Place chicken breasts on top.
Spoon sauce over the chicken, so it's fully submerged.
Cook in crockpot on LOW for 3 hours.
After 3 hours, remove chicken from the crockpot and cut into large, bite sized chunks. Place back into the sauce and stir to coat.
Serve immediately with sauteed bell peppers over rice. Top with chopped cilantro, crushed peanuts, and sliced green onions.
Notes
*For the bell peppers: I just warmed a nonstick pan over medium heat. Once hot, I added in olive oil and let it coat the pan. Then I added in large bell pepper chunks, seasoned with salt, and sauteed them until they were tender (about 10 minutes).
