In a small bowl, whisk together honey, minced garlic, soy sauce, and sriracha sauce until well combined.
Season the chicken breasts with salt and pepper on both sides. Heat the avocado oil in a large skillet over medium heat.
Once the oil is hot, add the chicken breasts to the skillet. Cook for about 5-7 minutes on each side, or until the chicken is golden brown and cooked through (internal temperature should reach 165°F/75°C).
Reduce the heat to low and pour the honey garlic sauce over the chicken in the skillet. Allow the sauce to simmer for about 2-3 minutes, basting the chicken with the sauce to infuse it with flavor.
Remove the skillet from heat and let the chicken rest for a few minutes. Slice the chicken and drizzle any remaining sauce over the top before serving. Garnish with chopped green onions, if desired.
