Heat the coconut oil in a large skillet over medium-high heat until shimmering.
Season the cubed chicken breast with sea salt and black pepper, then add to the skillet.
Sauté the chicken for 5-6 minutes until golden brown and cooked through, then push to the side of the pan.
Add the green curry paste to the empty space in the pan and stir for 30 seconds until aromatic.
Pour in the full-fat coconut milk, coconut aminos, and fish sauce, stirring to incorporate the curry paste.
Add the sliced red bell pepper and sugar snap peas to the sauce.
Reduce the heat to medium-low and simmer for 5 minutes until the sauce thickens and the vegetables are tender-crisp.
While the curry simmers, steam the cauliflower rice in a separate pan or microwave until tender.
Stir the fresh lime juice into the curry just before serving to brighten the flavors.
Divide the cauliflower rice into bowls, top with the chicken and curry sauce, and garnish with fresh cilantro.
