Slice sausage into bite-size pieces, and dice onions.
Cut potatoes into large chunks. If using baby potatoes cut in half.
In a large bowl toss together the potatoes, seasonings, and olive oil.
Preheat the griddle to about 400-degrees or medium heat.
Add the prepared potatoes to the grill. Cook under a dome flipping the potatoes about every 5-minutes until crispy and fork tender. This will take about 15-minutes.
Once the potatoes are done move them to one side of the griddle and turn the heat as low as it will go to keep them warm.
Add the onions and sausage to the other side of the griddle. Cook tossing often until the sausage is cooked and the onions are translucent. Since the sausage is basically pre-cooked it will not take long to cook.
Once the sausage is done cooking toss the potatoes with them, and remeove to serving platter.
Serve immediately or store in an airtight container for up to three days. Reheat in microwave.
