Bring a large pot of salted water to a boil. Add the orzo and cook according to package instructions until al dente, about 8-10 minutes. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add the chicken sausage, breaking it into pieces, and cook for 5-7 minutes until golden brown.

Add minced garlic to the skillet, cooking for about 30 seconds until fragrant.

Add cooked orzo and chopped broccoli, tossing to combine. Cook for an additional 3-4 minutes until broccoli is tender-crisp.

Season with salt, black pepper, and red pepper flakes to taste. Serve warm, topped with freshly grated Parmesan cheese.
