Cut the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat the coconut oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 5-6 minutes until golden and cooked through, then remove and set aside.
In the same skillet, add the green curry paste and stir for 1 minute until fragrant.
Whisk in the full-fat coconut milk and fish sauce, scraping up any browned bits from the bottom of the pan.
Add the sliced red bell pepper and sugar snap peas to the sauce, simmering for 3-4 minutes until tender-crisp.
Return the chicken to the skillet and stir to coat in the creamy sauce.
In a separate small pan, lightly sauté the cauliflower rice for 3 minutes until heated through.
Stir the lime juice into the curry and serve immediately over the cauliflower rice, garnished with fresh cilantro.
