Sausage and Peppers Sheet Pan Gnocchi

0 Heat the oven to 450°F.
1 Add the gnocchi, peppers, tomatoes, onion, and garlic to a large rimmed baking sheet. Drizzle with the oil and season with salt, dried oregano, red pepper flakes, and several grinds black pepper. Toss to coat and spread the mixture into an even layer.
2 Remove the casings from the sausage, if needed. Use your hands to pinch off bite-sized pieces of the sausage and drop over the veggies.
3 Roast, stirring halfway through, until the gnocchi and peppers are tender, the sausage is browned and cooked through, and the skins of the tomatoes are just starting to split, 20 to 25 minutes total.
4 Add the pepperoncini and brine to the baking sheet and toss to coat. Taste and season with salt, if needed. Divide between bowls and top individual servings with Parmesan, if using.
