Add a small drizzle of olive oil in a large skillet, and heat over MED-HIGH heat. Add both sausages and cook, breaking up meat with a wooden spoon as you cook, until sausage is browned, about 6-8 minutes.
Drain cooked sausage, then add to crockpot insert. Top with garlic powder, dried onion, cubed cream cheese, Ro-tel, hot sauce, pinch of salt and pepper, and 1 cup of the cheddar cheese.
Stir well, then cover and cook on LOW for 3-4 hours, or HIGH for 1.5-2 hours. Remove cover and sprinkle with remaining 1 cup of cheddar cheese, then cover again and cook another 10-15 minutes, until cheese is melted.
Sprinkle with minced chives and serve hot.
