Slice the chicken breast into thin, bite-sized strips and season lightly with sea salt.
Heat coconut oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté for 4-5 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.
Pour in the coconut milk, bone broth, fish sauce, and coconut sugar, whisking to combine the curry paste into the liquid.
Add the bell pepper, snap peas, and zucchini to the sauce and simmer for 3-4 minutes until the vegetables are tender-crisp.
Return the chicken to the skillet and stir to coat in the velvety sauce.
Meanwhile, steam or sauté the cauliflower rice in a separate pan for 3 minutes until tender.
Stir the fresh lime juice into the curry and serve immediately over the cauliflower rice, garnished with fresh cilantro.
