1Preheat your oven to 200°C (392°F).
Cook the gnocchi according to the package instructions, then drain and set aside.
Slice the red bell peppers and onion into thin strips.
In a large ovenproof skillet, heat the olive oil over medium heat.
Add the sliced onion and bell peppers to the skillet and sauté for about 5 minutes until they start to soften.
Add the cherry tomatoes to the skillet and cook for another 3 minutes.
Season the vegetables with black pepper.
Add the cooked gnocchi to the skillet and mix everything together.
Tear the mozzarella cheese into small pieces and scatter them over the top of the gnocchi and vegetables.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the cheese is melted and bubbly.
