Preheat your oven to 375°F (190°C) to ensure it's hot and ready for baking.
Carefully slice the tops off the bell peppers, removing the seeds and membranes inside. Place the cleaned peppers upright in a baking dish and set aside.
In a large skillet, heat the olive oil over medium heat. Add the finely chopped onion and minced garlic, sautéing until the onion becomes translucent and fragrant, which should take about 3 minutes.
Increase the heat to medium-high and introduce the ground chicken to the skillet. Cook, breaking it apart with a wooden spoon, until it's thoroughly browned—this should take about 5-7 minutes.
Once the chicken is browned, stir in the cauliflower rice, hot sauce, smoked paprika, onion powder, and a sprinkle of salt and pepper. Cook this mixture for an additional 3-4 minutes, allowing all ingredients to meld together and heat through.
Generously spoon the spicy buffalo chicken mixture into each bell pepper, packing them tightly to ensure they are full and flavorful.
Position the stuffed peppers upright in your baking dish. Cover them with aluminum foil to retain moisture and bake for 25-30 minutes. After that, carefully remove the foil and continue baking for an additional 10-15 minutes until the peppers are tender and slightly charred at the edges.
Once done, take the peppers out of the oven and allow them to cool slightly. Before serving, garnish each pepper with sliced green onions and a sprinkle of fresh cilantro for a burst of color and freshness.
Notes
Serve these vibrant stuffed peppers on a rustic wooden platter or individual plates, adding a few extra herbs around for a pop of color and freshness.
