Basically everything. I can tell you what I have eaten today.
You don't and you don't need to. If you eat a rich and varied diet with lots of vegetables and fruits, a balanced amount of carbs and proteins,and make sure you eat as much variety as you can you can be sure you are eating a diet that includes all of the nutrients you need.
Wrong approach. There is bot a uniquelist of healthy vegetables. The healthiest vegetables are always those that are in season and preferably local, which usually also happer to be tastier. Right now where I live it's bell peppers, zucchini, eggplant, and tomato season. Right now these vegetables are tastier and richer in nutrients. By the fall it will be artichoke, pumpkin, cauliflowers, and broccoli season: these will be delicious and full of nutrients.
There is no tiramisù without ladyfingers. You can make mascarpone cream, instead. Basically, you make the same cream you would make for mascarpone but serve it alone in cups, without lady fingers drenched in cognac and espresso.
You will need 250 grams of mascarpone, 2 eggs of such a quality that you can eat raw, 70 grams of castor sugar and some bitter cocoa or dark chocolate.
Separate the egg whites and yolks. Place the yolks in a bowl and beat until white and foamy, then add the mascarpone and work until completely combined. Whip the whites to stiff peaks, add about 1/3 of the whits to the cream, stir to combine, then add the rest of the whites and fold. Divide the cream in 4–6 small cups and place in the fridge for at least 2 hours. Serve dusted with cocoa or finely grated chocolate.
All of them. What you want to do is eating lots of vegetables, and in order to eat lots of vegetables you want them to be cooked so that they are tasty and make you want to eat them, and eat them a lot. You do not want eating vegetables to be a sacrifice, you want to make them shine so that on most days they are the center of your meal. In other words, you do not want sad vegetables, you want delicious:
Zuchine a scapece
Melanzane alla parmiggiana
Broccoli in padella
Polpettone di fagiolini
Pistacchi are a delicious nut. They are tasty and complement many different desserts.
Pistacchi are also nuts, and nuts are a delicious, tasty and healthy addition to everyone’s diet, rich in healthy fats and proteins. If you are not a vegan, a couple walnuts or brazilian nuts, or 4–5 pistacchi, almonds, hazelnuts, or a teaspoon of natural peanut butter are enough. Make sure you cycle the nuts you are eating regularly, as each nut has different properties. Keep a handful of nuts at home and eat a different nut each day, with a piece of artisanal crusty bread as a snack.
