1
Preheat the oven to 390F / 200C.
2
Slice the bell peppers in half lengthways and use a small spoon to remove the membrane and seeds. Rub a little olive oil over the peppers (inside and out) and place cut side up in a baking dish. Roast the peppers for 20 minutes.
3
Saute the diced onion, fennel and garlic in a little olive oil in your skillet for 4-5 minutes, until softened. Keep the heat fairly low so you don't burn the garlic!
4
Combine the ricotta cheese, egg yolk, fresh herbs, salt and black pepper (if using) and onion mixture in a bowl and stir well.
5
Once the peppers are cool enough to handle, spoon the ricotta mixture into the peppers, dividing equally between them. Roast the cheese stuffed peppers for 15-20 minutes or until they are tender.
