Usally I make what I am making for us, sometimes modified to be "lighter". Yesterday it was chicken breast, potatoes and green beans. The day before vegetable soup with parmigiano and olive oil.
Or I make steamed fish, with some olive oil, or pasta with tomato sauce or ricotta.
Sometimes I give her a boiled egg and vegetables, or an omelette and vegetables.
I make sure se eats proteins, fats (usualy olive oil), vegetables and carbs - if she's not eating pasta she gets bread or potaoes. She ends the meal with a fruit, right now it's grapes, a peach, watermelon or a couple of plums.
