In an oven proof skillet, melt butter. Add sliced sausage and cook until browned. Add onion and cook until translucent. Add garlic and cook about 30 seconds. Add salt.
Next, add in zucchini and stir well. Add black pepper to taste. Let cook until zucchini is softened a bit and juices release
Place tomatoes on top of zucchini/sausage mixture. Season with salt and pepper. Top with shredded cheese. Place in the preheated oven for 15-20 minutes or until cheese is melted and golden brown.
Serve over rice, scooping the juice out of the pan and drizzling over veggies and rice. Serve with shredded parmesan if desired.
