Heat 1 tbsp olive oil in a large skillet over medium-high heat.
Slice or crumble the sausage and cook 4–5 minutes until browned.
Remove sausage to a plate, leaving the fat in the pan.
Add the gnocchi directly to the skillet.
Cook 3–4 minutes, stirring occasionally, until lightly golden.
Add to the skillet: sausage, corn, tomatoes, roasted red peppers, tomato paste, ⅔ cup water.
If using onion, garlic, or paprika, add them now.
Simmer 5–6 minutes, stirring occasionally, until the sauce thickens.
Reduce heat to low.
Stir in ½ cup sour cream until the sauce becomes creamy.
Sprinkle 1 cup shredded cheese over the top.
Cover the skillet 1–2 minutes until melted.
Serve immediately.
