Start by removing all the florets from the broccoli head and transfer them to a bowl, add enough water to cover them and the white vinegar, let them soak for 15 minutes.
In a skillet, add the drizzle of olive oil, the unsalted butter and stir until melted.
Add the onion chopped into cubes and stir-fry until golden brown.
Add the carrots chopped into cubes and stir for 3 minutes.
Add the red bell pepper chopped into cubes, the salt, the black pepper, the dried basil and the crushed garlic, stir, cover the skillet and let it all cook for 5 minutes.
Turn off the heat and set aside.
Grate all the broccoli florets.
In a bowl, add the eggs, one pinch of salt, one pinch of black pepper, mix well then add the table cream, the grated parmesan cheese, one teaspoon of dried basil and the sweet paprika, mix until combined.
Once you’ve done that, in another bowl, add all the broccoli and the vegetable-stir, mix well, then add the egg mixture, mix well again.
Transfer all this mixture to a baking dish lined with nonstick baking paper.
Top it with another 50g of grated parmesan cheese.
