Preheat the oven to 400°F (200°C).
Sear the Chicken: Heat avocado oil in a large cast iron skillet over medium-high heat. Cook the chicken breasts for 5 minutes per side until browned.
Make the Hot Honey Sauce: In a bowl, whisk together honey, sriracha, garlic, salt, pepper, cayenne (if using), and crushed red pepper (if using). Set aside 3-4 tablespoons for later.
Sauté the Vegetables: Remove the chicken from the skillet and set aside. Lower the heat slightly and toss the zucchini and summer squash in the skillet for 1-2 minutes. Turn off heat.
Assemble in the Skillet: Add the shredded carrots over the squash, place the chicken breasts on top of the vegetables, and coat both sides of the chicken with the hot honey sauce.
Bake: Transfer the skillet to the oven and bake for 15 minutes (or until the chicken is fully cooked), stirring the vegetables halfway through.
Make the Ranch Drizzle: While the chicken bakes, whisk together the ranch drizzle ingredients in a small bowl.
Broil for Extra Flavor: Turn the oven to high broil and broil for 3-5 minutes until the sauce on the chicken caramelizes.
Rest & Cube the Chicken: Remove from the oven and let the chicken rest for 5 minutes. Cut into cubes and toss with the reserved hot honey sauce.
Assemble the Bowls: Divide the rice (or quinoa) into bowls, top with the sautéed vegetables and hot honey chicken, then drizzle with extra hot honey and ranch dressing. Add avocado slices and a squeeze of lime, if desired.
