In a large pot, heat the olive oil over medium heat. Add the sliced chicken sausage and cook until browned, about 5-7 minutes.
Add the minced garlic and red pepper flakes, sautéing for an additional 1-2 minutes until fragrant.
Stir in the orzo pasta and cook for 1 minute to toast slightly, stirring continuously.
Pour in the chicken or vegetable broth and bring to a boil. Lower the heat and simmer for about 10 minutes, stirring occasionally, until the orzo has absorbed most of the liquid.
Add the broccoli florets and dried oregano, cooking for an additional 5 minutes until the broccoli is tender and bright green.
Season with salt and pepper to taste, and stir in the grated Parmesan cheese until melted and creamy.
Remove from heat and let sit for a couple of minutes to thicken slightly.
Serve hot, garnished with fresh basil leaves on top.
Notes
Feel free to adjust the spice level by using spicy or mild sausage.
