Start by dicing the chicken breast, sweet potatoes, brussels sprouts, apples, onion, and garlic into uniform pieces for even cooking. Set your chopped ingredients aside.

Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the diced chicken breast, cooking it for about 8 minutes until golden brown and cooked through.

Add the sweet potatoes, diced onion, and brussels sprouts to the skillet, stirring them together with the chicken. Cook for approximately 10 minutes until fork-tender.

Fold in the diced apples, minced garlic, and fresh herbs, then sauté for another 5 minutes, allowing flavors to meld.

Taste and adjust seasoning with salt, pepper, or a pinch of red pepper flakes before serving.
