In a large pot or Dutch oven, melt the butter over medium heat.
Add the sliced sausage to the pot and cook for about 5-7 minutes, or until browned and cooked through.
Stir in the minced garlic, chopped onion, and diced bell pepper. Sauté for another 3-4 minutes, until the vegetables are softened and aromatic.
Add the orzo pasta to the pot, stirring well to combine with the sausage and veggies.
Pour in the chicken broth and bring the mixture to a gentle boil.
Add the halved cherry tomatoes and dried herbs. Season with salt and pepper to taste.
Reduce heat to a simmer, cover the pot, and cook for about 10-12 minutes, stirring occasionally, until the orzo is tender and most of the liquid is absorbed.
Once cooked, remove from heat and let it sit for a couple of minutes. Fluff with a fork and adjust seasoning if necessary.
Serve hot, garnished with chopped parsley and a sprinkle of grated Parmesan cheese.
Notes
Feel free to add other vegetables or adjust the seasoning to your taste.
