Preheat your Blackstone griddle or a large skillet over medium-high heat for about 3-4 minutes. Drizzle 1 tablespoon of oil onto the surface.

Add the sliced Yukon gold potatoes to the griddle, spreading them out in a single layer. Sprinkle with garlic powder, onion powder, smoked paprika, black pepper, and salt. Cook for 10-12 minutes.

Push the potatoes to one side of the griddle and add another tablespoon of oil. Place the sliced smoked sausage on the empty side and allow to brown for about 5 minutes.

Once the sausage is browned, toss in chopped onions, red bell peppers, and zucchini, stirring well. Cook for another 5-7 minutes until the veggies are tender but still crisp.

Check the seasoning and adjust as necessary. Mix everything together and let the flavors marry for a minute. Transfer to a serving plate and garnish with fresh parsley.
