Preheat oven to 425 degrees. Line large baking sheet with parchment paper.
Cut sweet potatoes into wedges. Try to keep them roughly the same size to ensure even cooking. Toss sweet potatoes with olive oil and then season with italian seasoning, garlic, salt and pepper. Toss well to ensure all sides are coated well.
Spread out in a single layer on baking sheet. Do not overlap as they will not get crispy.
Bake for 10 minutes, then flip all potatoes and bake for an additional 10 minutes or until brown.
While potatoes are baking, brown sausage in cast iron skillet or saute pan until cooked through. Drain on paper towel lined plate, if desired. Keep warm.
Remove fries from oven, and add to cast iron skillet or oven safe pan.
Top fries with sausage, peppers, red onions and gouda. Add to broiler until cheese is melted. Watch carefully, as it goes quick!
