To make this recipe vegetarian you can follow the same recipe as per the chicken, but substitute vegetables in it. These won’t need to be marinated and they can be put in the curry at the same point as the chicken would be added. It is very common to prepare this vegetarian (and vegan, therefore) curry with mixed vegetables, such as peas, carrots, onions, green beans, and potatoes, but also tomatoes, bell peppers, cabbage, and cauliflower add great flavor and texture to this recipe.
