Cut the washed zucchini in half lengthwise and hollow out the inside. Dry grill on both sides. Finely chop the waste from the courgettes and fry with the chopped onions, mushrooms and peppers, seasoning with salt and pepper, making sure the vegetables are crisp. Once cooled, stir in the Parmesan cheese and fill the courgettes, which are baked in the oven for about 10 minutes at 180°C. Whisk the egg yolks with the spinach until smooth, whisk the egg whites into stiff peaks, stir in the spinach mixture, flour, salami and season with salt. Put the mixture in a whipped cream bottle, drop in one whipped cream and refrigerate for 2 hours. Before serving, spray a paper cup with about 2 cm and bake for 1 minute in the microwave at 600W.
