Prepare a grill for medium-high heat.
In a large mixing bowl, combine the sausage, peppers, onions, potatoes, garlic, oregano, olive oil, and some salt and pepper. Toss to combine. Transfer the mixture to a large piece of heavy-duty foil and seal up into a pouch.
Place the pouch on the grill and cook for 30 to 35 minutes.
