Heat a large skillet over medium heat. Add the sliced chicken sausage and cook for about 5-7 minutes, stirring occasionally, until browned. This step adds flavor and texture to the sausage.

Add the diced onion, garlic, red bell pepper, and zucchini to the skillet. Sauté for another 5 minutes until the vegetables are tender. Stirring helps to evenly cook the vegetables and release their flavors.

Stir in the uncooked orzo, chicken broth, dried oregano, dried basil, red pepper flakes, salt, and black pepper. Bring the mixture to a boil.

Once boiling, reduce the heat to low, cover the skillet, and let it simmer for about 10-12 minutes, or until the orzo is cooked and has absorbed most of the liquid. Stir occasionally to prevent sticking.

Remove the skillet from heat and stir in the chopped spinach until wilted. This adds freshness and nutrients to the dish.

Serve the orzo mixture warm, garnished with grated parmesan cheese and chopped parsley for added flavor and presentation.
