We have made it a habit to eat salad once a day at lunch. It is often how I use up leftovers, too. As a main course, a good rule of thumb is 200 g vegetables, 60-80 g grains (rice, buckwheat, quinoa) and 100 g cooked legumes (chickpeas, edamame, fried tofu, tempeh) per person. Here is one of my favourite dressings.
